【摘要】 研究对L形短肢剪力墙构件截面的M-φ(弯矩-曲率)曲线进行了分析,在此基础上分析了L形截面曲率延性随轴压比及受压与受拉纵筋面积比的变化规律,结果表明:增大轴压比,延性降低;增大受拉与受压纵筋面积比,延性减小,因此建议在适当控制轴压比前提下应合理控制拉压纵筋配筋比.更多还原

【Abstract】 The M-φ curve of L-shaped short pier shear wall was analyzed.Based on the analysis,with the change of axial compression ratio and area ratio of tensile to compression reinforcement,the varying pattern of curvature ductility was analyzed.The results show that the ductility decreases with an increase of axial load ratio,and it also decreases with an increase of the area ratio of tensile to compression reinforcement.Therefore under the appropriate premise of an axial load ratio,the area ratio of tensile to compression reinforcement must be controlled reasonably.更多还原
