摘要
在已有的楔形单元弹性刚度方程的基础上 ,推导了它的弹塑性增量刚度方程 ,并利用所得到的结果研究了轴心和偏心楔形压杆在强轴平面内的非弹性稳定 ,得到了各种楔率下楔形压杆的柱子曲线和轴力
Inelastic incremental stiffness equations of tapered elements are established by employing the model of modified elastic?plastic hinges and the concept of tangent modulus,based on the developed elastic stiffness for the Timoshenko?Euler tapered elements.Planar inelastic stability of tapered columns,axially and eccentrically loaded,are studied with the proposed equations respectively.Column curves and thrust?moment interaction curves of tapered columns with various tapered ratios are presented.
