れる。When a horizontal load P is applied to the unit building Ua, the wall 11 of the building unit U1 and the wall 13 of the building unit U2 are deformed. The amount of their deformation is the spring constant K
Determined by 11 and the spring constant K 13 and a spring constant K 3. That is, the amount of deformation of the wall 11 having a large spring constant is small, and the amount of deformation of the wall 13 having a small spring constant is large. The ratio is an intermediate value between the case where the horizontal construction surfaces 3 and 3 have a pin structure and the case where the horizontal construction surfaces 3 and 3 have a rigid structure. Spring constant K 3 approaches the ratio of large HodoTsuyoshi structure. This means that only the bearing wall 11a in the wall 11 of the building unit U1, the horizontal Plane which has been determined by experiment and the spring constant K 13 in the wall 13 of the spring constant K 11 and the building unit U2 in the wall 11 in which a 11b spring can bearing wall 11a from the constant K 3 Prefecture, deformation amount of 11b and the pillar 21 to analyze whether equal to or less than a predetermined value. In this way, by setting each spring constant so that the deformation amount of the load-bearing walls 11a and 11b and the columns 21 is equal to or less than a predetermined value, a safe unit building can be designed, and the unit building is produced based on the design. be able to. As a result, the building unit U
An opening can be freely provided in the second wall 13 and restrictions on the position and size of the opening in the horizontal structure between the upper and lower floors are relaxed, so that the degree of freedom of layout is increased. Also, since the horizontal braces and the horizontal structure between the building units can be joined with ordinary bolts, the cost is low and the workability is excellent.
