Study on Cold-Formed Steel of Thin-Walled Housing for Dynamic Performance

摘要

Cold-formed steel structure is suitable for post-earthquake reconstruction since its good seismic performance and construction speed. Analyzing the dynamic characteristic of a two story office building by using the finite element software ANSYS. And the results show that: (1) in the time history analysis based on three types of seismic waves the lateral displacement of the structure and rotation between layers to meet the relevant specifications when confront the rare earthquake (2) Under the seismic loads, earthquake response acceleration amplification factor is smaller which indicating better seismic performance and it can be used in areas with high seismic intensity.
