高层结构塑性铰分布在不同荷载模式下的求解

目前,关于pushover水平荷载模式的研究成果已经有了很多。然而,已有的研究存在如下几个局限性:1.仅选取结构能力曲线和目标位移(顶端、层间)作为结构的性态指标;2.选取的结构模型多为中低层结构。为了考察pushover方法在高层结构的应用,选取了2个高层钢筋混凝土框架剪力墙结构,以结构的塑性铰分布为性态指标,分别进行不同荷载模式下pushover分析计算,给出了各荷载模式的优劣顺序。

Computation of plastic hinge distribution under different lateral load patterns

The studies on pushover lateral load patterns have been widely done,however there are some limitations in these studies,such as 1.Only capacity curve and target displacement are computed;2.The low-and medium-rise structural models are always adopted.In this paper,the important performance demands of plastic hinge positons of two high-rise structures are determined and compared under different lateral load patterns.
