摘要: 为分析施工缝对剪力墙结构抗震性能的影响,以3种工程中常见方式留设施工缝的剪力墙结构作为研究对象,并与无施工缝剪力墙作对比。利用ANSYS有限元软件建立有限元模型,对4种模型的滞回性能、延性、刚度退化等抗震性能进行对比分析。结果表明:施工缝的存在降低了剪力墙的延性和耗能能力,对结构的刚度退化影响不大,降低了剪力墙的抗震性能。从中找出最好的施工缝留设方法。Abstract: In the present paper,effect of construction joints on the seismic performance of shear wall structure was studied. Taking the shear wall structure whose construction joints were set by three common ways as the research object,which was compared with the shear wall structure without construction joints. The FEM software ANSYS was used to establish finite element models. The hysteretic behavior,ductility,rigidity degeneration and some other seismic performance of the four models were compared. The results show that the presence of construction joints could reduce the ductility and energy dissipation capacity of shear wall structure,which has little effect on the rigidity degeneration. The seismic performance of shear wall structure was reduced. At last,the best way of setting construction joints should be found out from the study.
