JP 2008-276474 A

To evaluate the earthquake resistance of an existing building, various information is required regarding the specifications, structure, components, and usage status of the existing building. Conventionally, when evaluating the earthquake resistance of an existing building, the user has had to input information such as specific design values and shapes. In this case, it takes time to input information, and the more information that needs to be input, the greater the input work burden becomes. Furthermore, for existing buildings, the location of the above information may not be known, in which case it is difficult to obtain the information that needs to be input.

Therefore, the present invention was made in consideration of the above problems, and its purpose is to provide a seismic evaluation device that can reduce the effort required to evaluate the seismic resistance of existing buildings.

The above problem is solved by the earthquake resistance evaluation device of the present invention, which is an earthquake resistance evaluation device that evaluates the earthquake resistance of an existing building, by including an identification unit that identifies a selection candidate selected by a user from among multiple candidates set for at least one item of the structure, components, and usage status of the existing building, and an evaluation unit that evaluates the earthquake resistance based on information associated with the selection candidate from information for each of the multiple candidates stored in association with each of the multiple candidates.

In the earthquake resistance evaluation device of the present invention configured as described above, when acquiring (inputting) the information required to evaluate the earthquake resistance of an existing building, it is sufficient to select a selection candidate that corresponds to the existing building from multiple candidates set in advance, and the above information can be acquired efficiently. This reduces the effort required to evaluate the earthquake resistance of an existing building.

In addition, in the above-mentioned earthquake resistance evaluation device, when there is content that does not correspond to any of a plurality of candidates for at least one item among the structure, components, and usage status of an existing building, a first reception unit is provided which receives input of information relating to that content, and the evaluation unit may evaluate the earthquake resistance based on the information associated with the selection candidate and the information input by the first reception unit.
According to the above configuration, when there is content that does not correspond to any of the multiple candidates, the seismic evaluation device can more efficiently acquire information required for seismic evaluation by accepting input of information related to the content. This can further reduce the effort required for evaluating the seismic resistance of existing buildings.

In the earthquake resistance evaluation device, the first receiving unit may receive an input of numerical information relating to the external shape of the existing building.
According to the above configuration, since the input of numerical information on the external shape of the existing building is accepted as content that does not correspond to any of the multiple candidates, the information required for the earthquake resistance evaluation can be obtained more efficiently. This can reduce the effort required for evaluating the earthquake resistance of an existing building.

In the earthquake resistance evaluation device, the first receiving unit may receive an input of analysis result information obtained by analyzing an image of the exterior of the existing building.
According to the above configuration, information on the external shape and dimensions of an existing building, which is information required for evaluating the earthquake resistance, can be obtained more efficiently. This can reduce the effort required for evaluating the earthquake resistance of an existing building.

In the earthquake resistance evaluation device, the first reception unit may receive an input of inspection information obtained by performing non-destructive testing on predetermined components of an existing building.
According to the above configuration, it is possible to efficiently obtain information necessary for evaluating earthquake resistance, such as information on whether a specific component of an existing building is a load-bearing element, thereby reducing the effort required for evaluating the earthquake resistance of an existing building.

In the above earthquake resistance evaluation device, the specifying unit may specify a selection candidate from among a plurality of candidates for at least one item based on a drawing of the existing building selected by the user.
According to the above configuration, the information required for evaluating earthquake resistance can be obtained more accurately based on drawings of the existing building, and as a result, earthquake resistance can be evaluated more accurately.

In addition, the earthquake resistance evaluation device may further include a second reception unit that accepts input of additional information regarding reinforcement of the existing building that is not included in the existing building at the current time for at least one item depending on the earthquake resistance evaluation result by the evaluation unit, and the evaluation unit may evaluate the earthquake resistance based on the information associated with the selection candidates, the information input by the first reception unit, and the additional information received by the second reception unit.
According to the above configuration, the earthquake resistance evaluation device can efficiently acquire additional information necessary to meet earthquake resistance requirements when reinforcing an existing building, thereby reducing the effort required when evaluating earthquake resistance.

The present invention provides a seismic resistance evaluation device that can reduce the effort required to evaluate the seismic resistance of existing buildings.

Specific embodiments of the present invention are described below. In this specification, the concept of "device" includes a single device that performs a specific function, as well as multiple devices that exist independently in a distributed manner but work together (in cooperation) to perform a specific function.

<<Outline of earthquake resistance evaluation method>>
First, an example of a seismic evaluation method using the seismic evaluation device of the present invention will be described with reference to Figures 1 to 3. A user who actually performs the seismic evaluation is assumed to be, for example, an employee of the remodeling department of a housing manufacturer.

Earthquake resistance evaluation is calculated according to commonly known methods, such as the evaluation methods used in earthquake resistance diagnosis for iron ore-based industrialized housing. Specifically, earthquake resistance evaluation involves calculating the strength required to meet the earthquake resistance standards set forth in regulations (required strength Qi) and the strength currently possessed by the existing building (possible strength Pd), and finally determining the ratio of the two, Pd/Qi.

The process of seismic assessment can be broadly divided into (1) collecting information necessary for the seismic assessment, (2) calculating strength based on the collected information, and (3) preparing the results of the seismic assessment in an official document format and submitting them to a public institution.

The seismic resistance evaluation device of the present invention uses a dedicated evaluation calculation tool (evaluation software) that performs all of the above steps (1) to (3) all at once. Specifically, the user installs the evaluation calculation tool on a general-purpose computer, starts the evaluation calculation tool, and follows the instructions displayed on the display screen to carry out the above steps (1) to (3).

The evaluation calculation tool has multiple sheets prepared to suit the work flow. Specifically, there is an input sheet corresponding to (1) above, a calculation sheet corresponding to (2) above, and an output sheet corresponding to (3) above. The user works while looking at each sheet displayed on the display screen. Each sheet is explained in detail below.

<Input sheet>
There are two types of input sheets, depending on whether there is content that does not correspond to any of the multiple candidates set for the structure, components, and usage status of the existing building. Specifically, one of the input sheets is selected depending on whether information on the floor plan is present. Figure 1 shows an input sheet for a pattern in which information on the floor plan is present, and Figure 2 shows an input sheet for a pattern in which information on the floor plan is not present.

As shown in Figures 1 and 2, common input items in both input sheets include the entry of basic data. The "basic data" includes the location of the existing building, the date of completion, the product (type of building being sold), snowfall classification, etc. In conventional seismic resistance assessments, the user must obtain information on the structure, components, and usage status of the existing building on-site, etc., and collecting data on this information was time-consuming. However, when this assessment calculation tool is used, multiple candidates for each of the items of the structure, components, and usage status of the existing building are automatically extracted from the database in accordance with the basic data. As a result, users only need to enter the basic data, reducing the effort required for information entry compared to conventional methods.

If the user selects the input sheet for manually inputting information about the floor plan, the user will input the "plan shape" in addition to inputting the above basic data, as shown in Figure 2. The "plan shape" refers to the external shape and dimensions of the existing building, and the user inputs coordinate information based on the shape and dimensions of the existing building that have been measured in advance. When the coordinate information is input into the input sheet, the plan shape is drawn in real time in a specified area of the display screen. The user continues inputting while looking at the drawn plan shape and comparing it with the external shape and dimensions of the existing building.
In this way, when the user inputs coordinate information of a planar shape, the input information is visualized on the display screen in real time, reducing operational errors and reducing the effort required for rework.

<Calculation sheet>
Once data entry into the input sheet is complete, the seismic evaluation device performs calculations by retrieving the corresponding information from the database based on the input basic data. The calculation sheet contains not only the ratio Pd/Qi values, but also detailed calculation results such as the strength values and weights of each component that makes up the existing building. The calculation sheet does not require any special work from the user, but when reviewing the calculation results later, the calculation sheet visualizes them, reducing the effort required for review.
<Output sheet>
Furthermore, based on the results of the calculations using the calculation sheet, an output sheet is created in the format of an official document, as shown in Fig. 3. As an example, Fig. 3 shows an outline of the "Seismic Diagnosis Check Sheet for Steel Industrialized Housing" by the Prefabricated Building Association. The output sheet can be printed and submitted to an official institution, reducing the time and effort required to re-create the output sheet in the format of an official document, as in the past. In the example shown in Fig. 3, a total of four sheets for general diagnosis (1) to (4) are printed.

As described above, by using a seismic evaluation device to perform seismic evaluation, the amount of work required for each task in the seismic evaluation is reduced.

First Embodiment
Hereinafter, with reference to Figures 4 to 9, we will explain a seismic evaluation system (hereinafter, seismic evaluation system S1) including a seismic evaluation device (hereinafter, seismic evaluation device 1) according to a first embodiment of the present invention (hereinafter, this embodiment).
As shown in Fig. 4, the earthquake resistance evaluation system S1 is composed of an earthquake resistance evaluation device 1 and a database 2. The earthquake resistance evaluation device 1 is composed of an information processing terminal such as a computer, and is capable of evaluating the earthquake resistance of existing buildings.

Various information related to existing buildings is stored in the database 2. To be more specific, the database 2 stores information stored in association with each of a plurality of products (existing buildings), more specifically, information related to the structure and components of existing buildings, etc. The database 2 also stores information necessary for identifying the usage state of an existing building, such as the degree of deterioration, earthquake region coefficient, and snow load, etc.
"Deterioration level" is an index showing the degree of deterioration of the structure of an existing building, and "earthquake region coefficient" is a coefficient set for each region and used to calculate earthquake force. "Snow load" is a load used in structural calculations for existing buildings, calculated by multiplying a unit load determined by the amount of snow by the horizontal projection area of the roof, etc.

<Earthquake resistance evaluation device>
As shown in FIG. 5, the earthquake resistance evaluation device 1 includes, as hardware, a processor 11, a storage device 12, a communication interface 13, an input device 14, and a display device 15.

The processor 11 is hardware (e.g., a CPU) for executing a set of instructions written in a program. The processor 11 executes various types of calculation processing based on the programs and data stored in the storage device 12, and controls each part of the seismic resistance evaluation device 1.

The storage device 12 includes, for example, a memory and a magnetic disk device, and in addition to storing various programs and data, also functions as a work memory for the processor 11. The storage device 12 may also include information storage media such as a flash memory and an optical disk.

The communication interface 13 includes, for example, a network interface card, and communicates with the database 2. In this embodiment, the communication interface 13 may use either wireless communication or wired communication.

The input device 14 includes, for example, a touch panel, a keyboard, buttons, etc., and accepts input from the user.

The display device 15 is configured to include, for example, a liquid crystal display device, an organic EL display device, etc., and outputs a screen based on the graphic data generated by the processor 11.

<Functions of the earthquake resistance evaluation device>
Next, functions provided in the earthquake resistance evaluation device 1 for implementing the above-mentioned processing will be described with reference to Fig. 6. The earthquake resistance evaluation device 1 includes an identification unit 21, a first reception unit 22, an evaluation unit 23, and a second reception unit 24.

The functions of each of the above-mentioned parts of the seismic evaluation device 1 are realized by the processor 11 controlling each part of the seismic evaluation device 1 based on the programs and data stored in the storage device 12. The seismic evaluation device 1 may read the above-mentioned programs from a computer-readable information storage medium, or may receive them via a communication network such as the Internet or an intranet.
The functions of the above-mentioned components of the earthquake resistance evaluation device 1 will be described in detail below.

(Regarding specific parts)
The identification unit 21 identifies a selection candidate selected by a user from among a plurality of candidates set for at least one item of the structure, components, and usage status of the existing building. In this embodiment, a plurality of candidates are set for all items, i.e., the structure, components, and usage status of the existing building.
Specifically, the identification unit 21 first displays a selection screen D1 in which multiple candidates are set for each of the items of structure, components, and usage status of the existing building, as shown in Fig. 7. The identification unit 21 accepts a candidate selected by the user from the multiple displayed candidates. In the example shown in Fig. 7, for example, the user selects product B as a selection candidate from multiple candidates, products A to Z, for the structure and components of the existing building.
A "product" represents the type of building being sold, and is composed of a combination of specifications, structure, components, etc. In the example shown in Fig. 7, products A to Z are displayed as options on the selection screen D1 as product types of existing buildings. The identification unit 21 receives product B and identifies it as a selection candidate.
The identification unit 21 also identifies a selection candidate from among multiple candidates for the usage status of the existing building by a similar procedure. In the example shown in Fig. 7, the selection screen D1 displays the completion date, location, snow accumulation classification, etc. as items for the usage status of the existing building. For example, the identification unit 21 allows the user to select the year and month when the existing building was completed, select the prefecture in which the existing building is located, and select the snow accumulation classification from general area, heavy snow area, etc.
In this example, the identification unit 21 sets multiple candidates for all items of the structure, components, and usage status of the existing building, but this is not limited to this, and multiple candidates may be set for at least one item.

(Regarding the first reception department)
The first reception unit 22 accepts input of information regarding content (hereinafter, non-candidate content) that does not correspond to any of the multiple candidates for at least one item of the structure, components, and usage status of an existing building.
In this embodiment, the non-candidate content corresponds to content that is not specified by simply selecting the type of product on the selection screen D1, for example, the "floor plan," which is one element of the structure of an existing building. There is a certain degree of freedom in the floor plan so that the customer's wishes are reflected, and even if a product is specified, the floor plan may not be specified. Examples of content related to the floor plan include the external shape (also referred to as the external dimensions) of the existing building for the structure of the existing building, and the positions of the load-bearing elements for the components of the existing building. In the following description, as an example, in this embodiment, the first receiving unit 22 receives input of numerical information related to the external shape of the existing building.

The first reception unit 22 receives user input regarding numerical information related to the external shape of the existing building, specifically, through an input screen D2 shown in Fig. 8. In the input screen D2, the user draws the planar shape of each floor of the existing building as the external shape of the existing building using one or more rectangular unit shapes. There is no particular limitation on the drawing method, but each unit shape may be drawn by, for example, specifying two representative vertices of each unit shape (specifically, the vertices located at both ends of a diagonal line) on the screen by operating, for example, a mouse. However, the method is not limited to this, and each unit shape may be drawn by directly inputting the coordinates of the two vertices.
The user performs the above drawing operation as many times as the number of unit shapes that make up the floor plan of each floor. As a result, the input of numerical information related to the external shape of the existing building is received by the first receiving unit 22. In addition, each unit shape drawn by the user is displayed on the screen each time a drawing operation is performed. As a result, the user can check the drawn unit shapes and the external shape of the existing building composed of the unit shapes on the screen at any time.

(About the evaluation section)
The evaluation unit 23 evaluates the earthquake resistance of the existing building based on the information stored in the database 2. A known method can be used to evaluate the earthquake resistance, and for example, an evaluation calculation adopted in the earthquake resistance diagnosis method for iron ore-based industrialized housing can be used. Specifically, for the existing building, the strength required to meet the earthquake resistance standard specified by the law (required strength Qi) and the strength currently possessed by the existing building (possessed strength Pd) are calculated, and the ratio Pd/Qi of the two is obtained. Here, if Pd/Qi is equal to or greater than a predetermined value, the building is evaluated as having earthquake resistance (the existing building will not collapse), and if the value of Pd/Qi is less than the predetermined value, the building is evaluated as having insufficient earthquake resistance (the existing building needs repair).
The predetermined value is generally set to "1.0", but may be changed to a larger value depending on how the safety factor is estimated.

In this embodiment, the evaluation unit 23 is capable of evaluating earthquake resistance in two patterns. The first pattern is used when there is no information regarding the non-candidate content accepted by the first acceptance unit 22. In this pattern, the evaluation unit 23 reads out information associated with the selected candidate from the information for each candidate stored in association with each of the multiple candidates in the database 2, and evaluates the earthquake resistance of the existing building based on the read out information.

The second pattern is used when there is information regarding non-candidate content that has been accepted as input by the first reception unit 22. In this pattern, the evaluation unit 23 reads information associated with the selection candidates from the database 2, and evaluates the earthquake resistance of the existing building based on the read information and the information that has been accepted as input by the first reception unit 22. In the following explanation of this embodiment, earthquake resistance will be evaluated using the second pattern.

Regarding the information associated with the selection candidates, for the structure of the existing building, the construction method and modules of the product selected from the multiple candidate products A to Z are read from the database 2 as information associated with the product (selection candidate). For the components of the existing building, information on the product's floors, walls, roof, strength elements, and weight expenditure elements is read from the database 2 as information associated with the product (selection candidate) selected from the multiple candidate products A to Z. For the usage status of the existing building, information corresponding to the selection candidate (for example, earthquake region coefficient associated with the location) is read from the database 2 as information associated with the selection candidate.

(Regarding the second reception section)
The second reception unit 24 receives input of additional information related to reinforcement of the existing building, which is not included in the existing building at the present time, for at least one item of the structure, components, and usage state of the existing building, according to the evaluation result of the earthquake resistance by the evaluation unit 23. When the evaluation unit 23 evaluates the existing building as being insufficient in earthquake resistance, the second reception unit 24 actively urges the user to input additional information. On the other hand, when the evaluation unit 23 evaluates the existing building as being earthquake-resistant, the second reception unit 24 may, for example, urge the user to input additional information, or may not require the input of additional information. The second reception unit 24 receives input of information related to a new bearing wall that is not included in the existing building at the present time, as the additional information. When the second reception unit 24 receives input of the additional information, the evaluation unit 23 reevaluates the earthquake resistance based on the information associated with the selection candidate, the numerical information received by the first reception unit 22, and the additional information received by the second reception unit 24.

(About the evaluation flow)
Next, the flow of the process (hereinafter, evaluation flow) executed by the seismic resistance evaluation device 1 will be described with reference to Fig. 9. Note that the evaluation flow shown in Fig. 9 is a process executed by the processor 11 of the seismic resistance evaluation device 1 based on a program stored in the storage device 12.

The evaluation flow is started when the user performs an operation to start the evaluation flow on the seismic resistance evaluation device 1. In the evaluation flow, first, a selection screen D1 (see FIG. 7) is displayed. Selection screen D1 displays multiple candidates for items related to the structure, components, and usage status of the existing building. When the user selects a candidate from the multiple candidates, processor 11 identifies the selection candidate selected by the user (S001). Processor 11 obtains information associated with the selection candidate from database 2.

Next, the processor 11 determines whether there is content that does not match any of the multiple candidates set for the structure, components, and usage status of the existing building (S003). If there is content that does not match any of the multiple candidates, input of information on that content is accepted (S004). Note that in this embodiment, as illustrated above, "content that does not match any of the multiple candidates" is, for example, content related to the floor plan. However, unlike the above example, if there is no content that does not match any of the multiple candidates, step S004 is skipped and the process proceeds to the next step S005.

In steps S005 and S006, the processor 11 calculates the required strength Qi and the available strength Pd, respectively, based on the information associated with the selected candidates and the information input by the first reception unit 22. If the value of Pd/Qi is equal to or greater than a predetermined value, the processor 11 evaluates that "the building will not collapse," and the evaluation flow ends at that point. On the other hand, if the value of Pd/Qi is less than the predetermined value, the processor 11 evaluates that "repair is required," and accepts the input of additional information (S008). Then, when the value of Pd/Qi becomes equal to or greater than the predetermined value as a result of the reevaluation, the evaluation flow ends.

<Effectiveness of the First Embodiment>
As described above, in the earthquake resistance evaluation device 1, when acquiring (inputting) information required to evaluate the earthquake resistance of an existing building, it is sufficient to select a selection candidate corresponding to the existing building from a plurality of candidates set in advance, and the above information can be acquired efficiently. This simplifies the information input when evaluating the earthquake resistance of an existing building, and reduces the effort required for the input.

The earthquake resistance evaluation device 1 of this embodiment also includes a first reception unit 22 that receives input of information on at least one item of the structure, components, and usage status of an existing building that does not correspond to any of a plurality of candidates.

According to the above configuration, when there is content that does not correspond to any of the multiple candidates, the seismic resistance evaluation device 1 can more efficiently acquire information required for seismic resistance evaluation by accepting input of information related to the content. This makes it possible to further simplify information input when evaluating the seismic resistance of an existing building and reduce the effort required for input.

Moreover, in the earthquake resistance evaluation device 1 of this embodiment, the first reception unit 22 receives input of numerical information related to the external shape of the existing building.
According to the above configuration, the earthquake resistance evaluation device 1 accepts input of numerical information on the external shape of the existing building as content that does not correspond to any of the multiple candidates, so that the information required for earthquake resistance evaluation can be acquired more efficiently. This further simplifies the information input when evaluating the earthquake resistance of an existing building, and further reduces the effort required for the input.

The seismic resistance evaluation device 1 also includes a second reception unit 24 that receives input of additional information regarding reinforcement of the existing building for at least one item depending on the seismic resistance evaluation result by the evaluation unit 23. The evaluation unit 23 also evaluates the seismic resistance based on the information associated with the selection candidates, the information input by the first reception unit 22, and the additional information received by the second reception unit 24.
According to the above configuration, the earthquake resistance evaluation device 1 can efficiently acquire additional information required to satisfy earthquake resistance requirements when reinforcing an existing building, thereby reducing the effort required for evaluating earthquake resistance.

As shown in FIG. 10, the earthquake resistance evaluation system S2 is composed of an earthquake resistance evaluation device 100, an image reading device 102, and an analysis device 103, and each device transmits and receives data via a network 101.

The image reading device 102 reads the drawings of the existing building selected by the user and imports them as image data. The analysis device 103 acquires the image data imported into the image reading device 102 via the network 101 and performs analysis of the image data. The identification unit of the seismic resistance evaluation device 100 identifies a selection candidate from among multiple candidates for at least one item of the structure, components, and usage status of the existing building based on the drawings of the existing building selected by the user (more specifically, the analysis results of the drawings). To explain using the example shown in Figure 7, the identification unit of the seismic resistance evaluation device 100 selects product B as a selection candidate from multiple candidate products A to Z based on the analysis results of the drawings of the existing building, and identifies the structure and components of the existing building.

As described above, in the earthquake resistance evaluation device 100 according to the second embodiment, the identification unit identifies a selection candidate from among multiple candidates for at least one item based on a drawing of an existing building selected by the user.
According to the above configuration, the information required for evaluating earthquake resistance can be obtained more accurately based on drawings of the existing building, and as a result, earthquake resistance can be evaluated more accurately.
