摘要
震后调查和试验结果表明,RC节点的破坏或失效可能是结构产生较大位移或整体倒塌的重要原因.为了预测结构变形,基于OpenSees分析平台建立RC节点数值模型,模型可有效考虑弯曲变形、纵筋粘结-滑移变形和节点核心区剪切变形.RC节点拟静力试验的数值模拟结果表明,所建立模型可较准确地模拟力-位移滞回曲线响应.
Abstract
The post-earthquake investigation and test results show that the failure or failure of RC joints may be an important reason for the large displacement or overall collapse of the structure.In order to predict structural deformation,a numerical model of RC joints is established based on OpenSees analysis platform.The model can effectively consider bending deformation,bond-slip deformation of longitudinal bars and shear deformation of joint core.The numerical simulations of RC joints quasi-static tests show that the established model can accurately simulate the response of force-displacement hysteresis curve.
