弹塑性静力分析法在结构抗震设计中的应用

Application of Push-over analysis in the seismic design of the frame structure

介绍了研究水平地震荷载作用下建筑物反应的静力非线性分析方法(Push-over方法)的基本原理,并考虑了结构进入塑性后因刚度改变造成的自振周期和侧向力的变化,利用Push-over方法对框架结构进行了弹塑性计算,得到了地震作用下的内力分布和变形情况,为抗震设计提供了依据。

This paper studied the Push-over method for analyzing horizontal earthquake response of buildings and considered the changes of natural frequency and lateral force of the structure due to plasticity of the structure led to structural rigidity changes. The internal force distribution and the displacement of the structure are obtained by Push-over analysis, which can be used for the seismic design of the building.
