摘要
由于高阶振型的影响,用Pushover方法进行高层钢结构性能分析仍存在很多问题.采用不同的水平加载模式对多层和高层钢框架结构进行多遇和罕遇地震作用下的Pushover分析,得到了结构顶点位移、楼层位移和层间位移角等结果,并对结构的抗震性能进行了多方面的评估,对如何选取更合理的加载模式用于高层钢结构的性能分析做了一定的探索工作.
Because of higher-order vibration modes,there are a lot of problems with in high-rise steel structural pushover analysis.Pushover analysis method is adopted with the aid of the SAP2000 software to analyze the multi-layer and high-rise steel structures in small earthquakes and rare earthquakes.In the analysis various lateral loading patterns are considered,and the corresponding results,including the nonlinear top-story displacement,story displacement and the distribution of story drifts,are obtained.In order to find a more reasonable loading pattern of high-rise steel structural performance,the seismic performance of structures is assessed.
