摘　　要：内嵌聚苯板复合剪力墙是一种新型的承重多功能墙板,对3个内嵌聚苯板高强混凝土复合剪力墙模型进行低周反复荷载试验,对高强混凝土复合剪力墙的承载力、刚度及其退化过程、延性、滞回特性及破坏特征进行研究,重点研究斜向钢筋支撑配筋率不同对墙体抗震性能的影响。试验结果表明:在3个高强混凝土复合剪力墙构件中,带有斜向支撑钢框架高强混凝土复合剪力墙的抗震性能比普通钢框架高强混凝土复合剪力墙明显提高,而且随着配筋率的提高,高强混凝土复合剪力墙的承载力、后期刚度、延性等也随之明显提高。High strength concrete shear wall embedded polystyrene foam is a new type of multifunetion bearing wall. Cyclic loading experiments on three models of these walls are carried out. The bearing capacity, stiffness and its attenuation, ductility, hysteretic property and failure phenomena are investigated. The effects of different reinforcement ratios of inclined steel braces on the seismic performance of the wall are discussed. It is shown that the seismic behavior of the shear wall with inclined brace of steel trusses has been improved much more than that of normal shear wall. Further more, with increasing of the reinforcementratio, the bearing capacity, the after-stiffness and the ductility have also been improved evidently.
