| 摘 要： | MMPA方法是将按类似弹性振型组合方法对各阶振型侧力模式下pushover分析计算结果进行耦合,按得到结构的弹塑性地震响应的一种非线性静力分析方法。该方法考虑了高阶振型对于高层结构的地震反应的影响。本文分别对两栋不同结构形式的规则高层结构进行了均匀侧力分布,第1振型水平侧力分布和MMPA方法的静力非线性分析。通过与弹塑性动力时程响应分析结果的比较分析,对MMPA方法计算高层建筑结构的准确性进行了评估。

| Abstract: | MMPA method is a nonlinear pushover method which obtains structural nonlinear earthquake response by means of combining the results of nonlinear pushover analysis under modal shape loads.The MMPA method can well consider the effects of higher modes for high-rise buildings.In present paper,two different structure style regular reinforced concrete high-rise buildings were performed with nonlinear pushover analysis by using uniform lateral load distribution,1st mode shape lateral load distribution and MMPA met... |
