| 摘 要： | 根据变形能力计算不同位移延性需求剪力墙轴压比限值。由剪力墙位移延性推导曲率延性，由屈服曲率和曲率延性计算墙体极限曲率，根据箍筋约束混凝土应力-应变关系确定剪力墙边缘构件混凝土的极限压应变，确定剪力墙位移延性轴压比限值。

| Abstract: | Different displacement ductility demands different ultimate value of axial compression ratio in Shear wall which can calculate by different deformation. Curvature ductility is derived by displacement ductility of shear wal , and ultimate curvature of the wal is calculated by the yield curvature and the curvature ductility. The ultimate compressive strain of concrete which is used in edge components in shear wal is determined according to the relationship of stress-strain of concrete confined by hoop steels. The paper determines the ultimate value of axial compression ratio of shear wal . |
