摘要
预制装配式剪力墙结构的抗震性能主要取决于结构水平连接和竖缝连接,本文研究模型为一种新型连接形式,即预制装配式剪力墙钢板抗剪键,该连接形式由北京市建筑设计研究院有限公司设计。本文主要通过对该种连接形式进行试验和数值模拟研究,分析该种连接形式受力性能,包括承载力、抗震性能和延性性质。试验共设计了5组尺寸相同的试件,在不同轴压作用下进行低周往复加载得出滞回曲线和骨架曲线,并采用ABAQUS有限元软件对其模拟,得出数值结果与试验结果进行对比。结果表明:该种连接形式具有一定的承载力,在轴压为正时试件具有很好的延性,试验和数值结果吻合较好。表明该种连接可以运用到实际工程结构中。
The seismic performance of pre-fabricated wall structure depends on the level and vertical joint connection. The steel plate shear connector is a new type of connection in pre-fabricated concrete wall. This kind of connection is designed by the Beijing Architectural Design Institute Co. Ltd. The form of test and numerical simulation is mainly studied,and the analysis of the connection focus on force performance including bearing capacity,ductility and seismic performance properties. Five sets of the same size specimen which were put on low cyclic loading with different axial pressure are designed,and the hysteretic curves and skeleton curves are gotten. The ABAQUS were applied to simulate them. The numerical results are compared with the experimental results. The results show that the connection has certain bearing capacity and good ductility with positive axial pressure. The experimental and numerical results are in good agreement. Analysis results show that this kind of connection can be applied to actual engineering structure.
