高层结构塑性铰分布在不同荷载模式下的求解
|
摘要
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。
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.
