摘　　要：为优化高层建筑短肢剪力墙结构设计,文中对不同轴拉比、剪跨比和含钢率下短肢剪力墙抗震性能展开试验研究。结果表明,无轴压试件的破坏模式为压弯破坏,拉弯试件的破坏模式为剪切-拉弯耦合破坏。随着位移角的增加,短肢剪力墙水平荷载-位移角曲线表现S型;短肢剪力墙的滞回曲线表现为梭形。总之,轴拉比越大,含钢率越低,剪跨比越大,短肢剪力墙的刚度、承载性能和延展性能均越差。In order to optimize the design of short-leg shear wall structure in high-rise buildings,the seismic performance of short-leg shear wall under different coaxial ratio,shear span ratio and steel content was investigated experimentally.The results show that the failure mode of non-axial compression specimens is compressive bending failure,while the failure mode of tensile bending specimens is shear-tensile bending coupling failure.With the increase of the displacement Angle,the horizontal load-displacement Angle curve of the short-leg shear wall is Sshaped.The hysteretic curve of short shear wall is fusiform.In short,the higher the axial pull ratio,the lower the steel content and the higher the shear span ratio,the worse the stiffness,bearing capacity and ductility of the short-limb shear wall.
