摘要:
为在高层建筑静力弹塑性分析中考虑高阶振型的影响,在模态Pushover分析方法基础上,采用能力谱法替代原有的动力时程分析,在现行规范加速度反应谱基础上计算结构各振型等效单自由度(ESDOF)体系各性能水平的位移反应,然后将其转化为相应多自由度(MDOF)结构的位移反应,并通过振型组合方法(SRSS)求得结构的总位移反应,用其与剪力墙的目标位移进行比较,判断设计结果是否满足性能目标要求。结果表明:该方法较合理地反映了结构在设计地震作用下的位移需求。
Abstract:
In order to calculate the influence of high-order vibration modes for elastic-plastic analysis of high-rise buildings, based on modal Pushover analysis(MPA)method, the capacity spectrum theory was used to take the place of dynamic time-history analysis. Converting the acceleration response spectrum of current code into displacement response spectrum, the displacement response of equivalent single degree of freedom system(ESDOF)in each vibration mode could be calculated by capacity spectrum method. Then, the displacement response of multiple degree of freedom(MDOF)could be obtained too, and it was used to compare with the objective displacement of each performance level, judging whether the structure satisfied its performance objective requirements or not. The results show that the method is reasonable to reflect the requirements of the structure under design earthquake displacement.
