摘要
本文设计了采用三种新型连接形式的预制叠合板式剪力墙和一片作为对比的整体现浇剪力墙构件,对试件进行低周往复荷载试验,结果显示三片预制墙片抗震性能良好。结合试验现象,基于通用开源有限元程序OpenSees建立考虑连接节点处粘结滑移的剪力墙模型,对试验所测构件进行数值模拟,计算结果与试验结果吻合良好,验证了数值模拟方法的准确性。
In this paper,three precast composite shear wall specimens with different innovate connection joints and one monolithic casting shear wall specimen are designed and constructed.Quasi-static tests of the four shear wall specimens were conducted.The test results indicated that seismic performance of the three precast specimens is as well as that of monolithic casting shear wall specimen.Based on the software OpenSees and combined with the test results,finite element models(FEM)considering the bond-slip relationship were developed,and numerical simulations of precast composite shear wall specimen are performed by using the FEM,the numerical simulation results agrees with the test results well.
