Description

A multi-story fabricated steel structure frame-eccentric support system

technical field

The invention relates to a multi-high-rise assembled steel structure frame-eccentric support system, which belongs to the technical field of structural engineering.

Background technique

According to the statistics of the China Iron and Steel Association, my country's steel output exceeded 700 million tons in 2011, ranking first in the world's steel output for 16 consecutive years. The development of the structure is seriously lagging behind. At present, in developed countries, such as the United States and European countries, the steel structure construction area accounts for more than 50% of the total construction area, and Japan accounts for 80%, while our country accounts for less than 4%.

Moreover, traditional buildings have disadvantages such as long construction period, serious waste of materials, and heavy pollution during construction, which cannot meet the needs of rapid reconstruction after the earthquake. Therefore, after learning the tragic lessons of the Wenchuan earthquake, it is imperative to innovate the industrialized assembly high-rise steel structure system. Relevant research not only conforms to the national development strategy of promoting the use of steel structures and promoting housing industrialization, but also meets the needs of energy conservation and emission reduction, and has broad development prospects and application value.

In the traditional steel frame structure system, the lateral stiffness of the structure is small, and the displacement between floors is large under the action of wind and earthquake loads, which is difficult to meet the comfort requirements. The new multi-story steel structure frame-eccentric support system adds horizontal and vertical steel supports on the basis of the steel frame to form energy-dissipating beam sections, which improves the lateral stiffness and plastic energy dissipation capacity of the structure, and improves the seismic performance of the structure .
