【摘要】 提出了内藏钢桁架混凝土组合剪力墙,即桁架与剪力墙、型钢与混凝土的双重组合剪力墙．为了比较内藏钢桁架混凝土组合剪力墙、普通混凝土剪力墙和钢桁架的抗震性能,本文进行了3个1/3缩尺试验模型的抗震性能试验,包括1个普通混凝土剪力墙、1个内藏钢桁架混凝土剪力墙和1个钢桁架．在试验研究基础上,对比分析了各试件的承载力、滞回特性、耗能能力及破坏特征．试验表明:普通混凝土剪力墙与钢桁架组合而成的剪力墙的抗震能力,比普通混凝土剪力墙和钢桁架单独应用的抗震能力之和明显提高．更多还原

【Abstract】 In this paper, a new composite shear wall with concealed steel truss was put forward. It included two kinds of composition. One was composition of steel truss and RC shear wall, the other is composition of profiled steel and concrete. In order to compare the seismic performance of shear walls with concealed steel truss, normal shear wall and steel truss, experimental study on seismic behavior of three 1/3 scale specimens, including a normal shear wall, a shear wall with concealed steel truss and a steel truss, were carried out based upon the experimental study, the bearing capacity, hysteretic property, energy dissipation and failure mode of the specimens were contrastively analyzed. The experimental results show that the seismic bearing capability and energy dissipation capacity of shear wall with concealed steel truss excelled the total of normal shear wall and steel truss.更多还原
