摘要
为验证采用数值模拟方法研究抗震钢筋混凝土梁柱边节点抗剪性能的可行性,借助ABAQUS软件对配置HRB400E钢筋的混凝土梁柱边节点进行了建模模拟,并将模拟结果跟已有的试验结果进行对比,结果表明:模拟试件应力云图和裂缝开展图可以表现试件的破坏过程,经对比发现与试验破坏过程一致;模拟试件传力机理与试验试件相比略有不同;模拟骨架曲线与试验骨架曲线大致发展趋势是一致的,存在差异的主要原因是模拟中钢筋混凝土接触的选择和试验客观条件的影响,下一步可对模型接触关系做进一步调整以提高模型的精确度。
To verify the numerical simulation method to study the feasibility of seismic shear performance of reinforced concrete exterior joints,in this paper,with the help of ABAQUS software,configure HRB400 E reinforced concrete exterior joints modeling simulation,and the simulation results compared with the existing experimental results,the results show that:The simulated stress cloud diagram and crack development diagram can show the failure process of the specimen,which is consistent with the experimental failure process by comparison.The force transmission mechanism of the simulated specimen is slightly different from that of the test specimen.Simulation development trend of skeleton curve and test curve is consistent,the main reason for the difference is in the choice of reinforced concrete contact and simulation test the influence of objective condition,the next step for the contact relation between the model for further adjustment in order to improve the accuracy of the model.
