小高层钢结构住宅抗震性能研究

Seismic performance on medium high-rise steel structure residence

从研究钢结构小高层结构体系的抗震性能出发,分别建立了钢框架、钢框架支撑2种三维空间有限元模型。利用有限元软件分别对2种模型进行了7度和8度抗震设防烈度下的动力特性分析和动力时程分析,并对两种模型动力时程分析结果中的顶点位移和层间位移进行了对比,提出了设置钢支撑对实际工程中小高层钢结构住宅抗震性能的影响。

The three- dimensional space model of the steel frame and the braced steel frame were estab- lished for studying the lateral resistant performance of small - tall steel structure residence. The two mode- ls＇ dynamic analysis and time - history analysis on the 7 and 8 degree earthquake intensity were studied by using finite elements software. The two models＇ the relation of the coping displacement and relative storm displacement were compared, and the seismic performance of setting steel - brace on the practical engi- neering was proposed.
