考虑楼板效应的钢结构罕遇地震反应分析

以10层钢结构为研究对象，在罕遇地震作用下，通过ANSYS有限元数值方法，对纯框架结构及不同支撑结构在考虑楼板作用与不考虑楼板作用的情况下结构的地震响应进行了比较分析，结果表明：同种结构在楼板作用下耗能能力降低，结构的整体刚度增加，自振周期减小，地震反应增强。

Analysis on rare earthquake action of steel structure by considering floor effect

With 10-layer steel structure as the research object,under the rare earthquake action,by using ANSYS finite element numerical method,it carries on comparative analysis on earthquake reaction of the pure frame structure and different bearing structures under the condition of taking the floor effect into and not into consideration.The results show that: the energy consumption ability of the same structure reduces under the floor effect,the overall rigidity of the structure increases,the self-vibration period ...
