半刚性端板连接多层钢框架的Push-over分析
Push-over Analysis of Multistory Steel Frame with Semirigid End-plate Conections
摘要
Abstract
Because of the absence of calculation theory and design method for semirigid connection, it is still calculated and designed as rigid connection in our country, which leads to significant differences between the calculation result and the real stressed state. In this paper, an FEM model of a multistory steel frame with semirigid end-plate connections was set up with Sap2000, and modal analysis, spectrum analysis and pushover analysis on the model were calculated. The dynamic properties of the steel frame with semirigid end-plate connections were discussed, and the influence of semirigid connections on the multistory steel frames design was studied. The results have shown that the steel frames with semirigid connections are different from that with rigid connections. The flexibility of the connections affects the behavior of the frames, and their influences can not be ignored in the design and analysis of steel frames.关键词
