介绍了Pushover分析的基本方法,阐述了几种典型的水平侧向力分布的原理特征及选取原则,并结合某超高层框架剪力墙工程实例,分析了不同加载模式下结构薄弱部位发展、层间位移角大小、性能点的出现等情况,最后提出了薄弱构件的加强措施。
The basic method of pushover analysis is introduced. The principle and selection principle of several typical horizontal lateral force distributions are expounded. Combined with the engineering example of a super high-rise frame shear wall, the paper analyzes the development of weak structure parts under different loading modes, The size of the displacement angle, the appearance of the performance point and so on. Finally, some measures to strengthen the weak components are put forward.
