摘要:

在传统的弯曲截面理论分析方法基础上,结合钢筋混凝土弯剪破坏柱的受力特点,对太平洋地震工程研究中心(PEER)钢筋混凝土柱抗震性能试验数据库中的试验数据进行分析,提出了一种确定弯剪破坏钢筋混凝土偏心受压构件荷载-变形关系的实用方法。研究结果表明:采用该方法计算得到的荷载-变形曲线与试验结果吻合良好,可用于确定地震作用下弯剪破坏钢筋混凝土偏心受压构件恢复力模型的骨架曲线。

Abstract:

In order to model the lateral load-deformation relations of reinforced concrete eccentric compression members with flexural-shear failure, a simplified method was presented based on the conventional section analysis techniques and test data analysis in the Pacific Earthquake Engineering Research Center(PEER)structural performance database, and mechanical behaviors of flexural-shear failure columns were also considered. The study results show that the predicted load-deformation curves match the experimental data with adequate accuracy, so it can be used to simulate the skeleton curve of hysteresis model of reinforced concrete eccentric compression members with flexural-shear failure subjected to seismic load.
