低层冷弯薄壁型钢结构抗震性能分析

Shock Resiatance Analysis on Low Cold-formed Thin-Walled Steel Structure System

四川汶川大地震后，大量的灾区房屋急需要重建，低层冷弯薄壁型钢结构住宅体系是一种理想的选择。以某钢结构企业捐献给灾区的两层冷弯薄壁型钢小学试点房为研究对象，按照现行的建筑抗震设计规范，基于单片墙体的抗剪能力，采用底部剪力法进行了整体结构的抗震性能分析。结果表明，该建筑所采用的组合墙体构造能满足我国规范的抗震设防要求，此类结构体系适合建造于灾区。

A large number of residential buildings needed to be rebuilt in disaster areas after Wenchuan earthquake in Sichuan province,low-rise cold-formed thin-walled steel residential building system was an ideal choice.A two-floor cold-formed steel primary school building,which was donated to the disaster areas,was taken as an example,according to our current national seismic design code,integral seismic analysis of the building was performed by using the base shear method based on single wall's shear design strength.The results show that the conformation of composite walls used in this building satisfies requirement for earthquake resistance of our national requirements,this structure system is applicable in disaster areas.
