摘要

采用有限元软件ABAQUS中的显示动力分析模块ABAQUS/Explicit

分别对钢筋混凝土剪力墙准静态和高应变率动力荷载作用下的响应进行了数值模拟;通过比较高应变率与准静态加载下的分析结果

探讨了地震作用下应变率对钢筋混凝土剪力墙动态性能的影响。研究结果表明

受应变率效应的影响

混凝土和钢筋的动态力学行为发生了变化

动力荷载作用下的钢筋混凝土剪力墙的承载能力有一定程度的提高

故在对钢筋混凝土结构进行抗震分析时

应适当考虑应变率效应。

Abstract

The response of the reinforced concrete shear wall under quasi-static load and dynamic load with high strain rate are analyzed using the ABAQUES/Explicit module in finite element software ABAQUES.The results of high strain rate are compared with those of quasi-static to study the effects of strain rate on dynamic behavior of reinforced concrete shear wall.Results show that the dynamic behavior of concrete and steel changes greatly when the strain rate effects are taken into account.For reinforced concrete shear wall subjected to dynamic load

there is an increase in load carrying capacity and stiffness.The strain rate effects should be considered properly in the seismic analysis of reinforced concrete structures.
