摘　　要：运用Matlab软件计算了轴压比n=N/fcA,受压与受拉纵筋面积比A's/As不同时构件几种弯矩与曲率,分析了T形截面短肢剪力墙曲率延性的影响,绘制了M-ψ曲线。表明随轴压比n增大,延性降低,随纵筋面积比A's/As增大,延性提高,表明合理控制轴压比n,适当提高受压与受拉纵筋面积比是改善其抗震性能的有效措施。Bending moment and Curvature were calculated in matlab for shear walls, and different ratio of axial compressive force n = N/fcbh and the rebar ratio As/As of short shear walls with T- shaped cross section are analyzed in this paper, and drew M - φ curves. The results indicate that with the increase of ratio of axial compressive force, the ductility decrease. And the increase of rebar ratio As/As, the ductility improved. There- fore, by decreasing A, and increasing As/As, the earthquake re- sistance performance of the shear walls can he made better.
