摘　　要：剪力墙构件是现代高层建筑结构中的主要抗侧向力构件。为了对比型钢桁架混凝土组合低矮剪力墙与型钢框架混凝土组合低矮剪力墙以及普通钢筋混凝土低矮剪力墙在地震作用下的抗震性能,本文进行了四榀1/4缩尺模型的低矮混凝土剪力墙在单调和低周反复荷载作用下的对比试验,其中单调加载试验包括一榀内置型钢桁架的型钢混凝土组合低矮剪力墙,反复加载试验包括一榀普通钢筋混凝土低矮剪力墙、一榀内置型钢框架的型钢混凝土低矮剪力墙和一榀内置型钢桁架的型钢混凝土低矮剪力墙,给出了各试件的刚度、承载力、变形、延性和破坏形态等试验结果,并对其进行分析。试验结果表明,在这三种墙体中,型钢桁架混凝土组合低矮剪力墙的承载力、变形能力、耗能能力较其他类型剪力墙好,并为型钢桁架混凝土组合低矮剪力墙在实际中的应用提供了试验依据。Shear wall element is an important element to resist the lateral load, wall embedded with steel shapes is not detailed yet. To analyze the difference of however, the research on the shear the seismic behavior among the three kinds of shear walls,namely steel reinforced concrete truss shear wall, steel reinforced concrete frame shear wall and common reinforced concrete shear wall, we performed monotonic and cyclic lateral load test on four 1/4 scaled lowrise concrete shear wall specimens, including one piece of common steel reinforced concrete shear wall, one piece of concrete shear wall embedded with steel shape frame and two pieces of concrete shear wall embedded with steel shape truss, and analyzed their stiffness, load-bearing capacity and failure mode. The results indicate that among these three kinds of elements, the concrete shear wall embedded with steel shape truss possesses greater strength, ductility and energy dissipation than the other two.
