摘　　要：通过数值积分法研究了楔形变截面压弯构件平面内弹塑性弯曲失稳问题 ,然后以大头截面为计算截面 ,建立了变截面压弯构件的轴向荷载和端弯矩之间的相关关系。The in-plane elastoplastic bending instability of the tapered bending members is studied by numerical integration;and then a correlation between the axial load and end moment of the tapered bending members is also established by taking a larger end section as the one of the calculation.

关 键 词：楔形变截面 压弯构件 平面 弹塑牲 稳定 相关曲线 数值积分法 轴向荷载
