摘要

圆钢管混凝土边框内藏桁架剪力墙是一种新型组合剪力墙。为了解这种剪力墙的抗震性能,进行了3个1/5缩尺试件的低周反复荷载试验。3个试件中,1个为圆钢管混凝土柱框架结构,1个为圆钢管混凝土边框-钢桁架结构,1个为圆钢管混凝土边框内藏钢桁架剪力墙。基于试验,对比分析了各试件的承载力、刚度及其退化过程、滞回特性、耗能能力及破坏特征。试验表明:圆钢管混凝土边框内藏钢桁架剪力墙承载力高,刚度大,耗能能力强,延性良好。
Shear wall with concrete filled round steel tube columns and concealed steel trusses is a new kind of composite shear wall.In order to measure its seismic performance,three 1/5 scale specimens,including one frame with concrete filled round steel tube columns,one frame with concrete filled round steel tube columns and steel trusses,and one shear wall with concrete filled round steel tube columns and concealed truss,were tested under cyclic loading.Based on the experimental study,the load-carrying capacity,stiffness and its attenuation,hysteretic property,energy dissipation and failure phenomena of each specimen were comparatively analyzed.The study shows that the seismic performance of shear wall with concrete filled round steel tube columns and concealed steel truss has greater load-carrying capacity,higher stiffness,greater energy dissipation capacity and better ductility.
