两种抗剪理论在节点拟静力试验数值模拟中的应用

Two shear theories application in numerical simulation of joint pseudo-static test

基于Open SEES中的节点宏单元模型对节点拟静力试验进行数值模拟,采用混凝土构件的抗剪理论修正的斜压场理论和固定角软化桁架理论分别对节点核心区的剪切应力应变曲线定参,对比了不同的抗剪理论对节点拟静力试验数值模拟的影响。

The numerical simulation of joint pseudo-static is done based on Open SEES joint macro model. The shear stress-strain curves are defined by modified compression field theory and fix angle softened truss model theory,comparative effects of two shear theories application in numerical simulation of joint pseudo-static test.
