【摘要】 以某高层建筑结构的抗震性能分析为例,对该结构的主楼及地下室在内采用整体模型,选用SATWE、PMSAP两个程序进行电算,通过多遇地震弹性分析和罕遇地震静力弹塑性分析,考察结构在弹性分析下的变形和弹塑性分析下的塑性铰发展机制,找出薄弱部位,并重点加强.分析结果表明,对高层建筑尤其是复杂结构的整体抗震性能进行综合分析评价是必要且可行的.更多还原

【Abstract】 Taking a high-rise building structures seismic performance analysis as an example,the structure of the main building and the basement,including a holistic model,selection of SATWE,PMSAP two procedures computing,through a multi-event of seismic elastic analysis,and rare earthquake Pushover analysis,examining the structure of elastic analysis and elastic-plastic analysis of deformation under the plastic hinge development mechanism,to identify weak areas,and focus on strengthening.The results show that for high-rise buildings,especially the complex structure of a comprehensive analysis of the overall seismic performance evaluation is necessary and feasible.更多还原
