摘　　要：通过对普通混凝土低剪力墙,内藏钢筋桁架、内藏钢桁架低剪力墙的模型试验研究,发现内藏钢筋桁架、内藏钢桁架低剪力墙的开裂荷载和极限荷载都比普通混凝土低剪力墙高,极限载荷分别比普通剪力墙提高29.1%和73.9%,延性系数分别比普通剪力墙提高31.9%和67.4%.这说明它们具有良好的弹塑性变形能力,是一种性能良好的结构构件.Through the experimental study of low shear wall of normal concrete, inner steel truss and inner truss models, it was proved that the cracking load and ultimate load had been increased in the low shear wall of inner steel truss and inner truss. The ultimate cracking load had increased 29.1% and 73.9% re- spectively and the ductility had increased 31.9% and 67.4% respectively than low shear wall of normal concrete. Furthermore, the good plastic deformation had been proved that existed in inner steel truss and in- ner truss models. Then a conclusion that it can be drawn an structure component with good properties.
