摘 要: 本文回顾了圆管形截面杆件弹塑性弯曲曲率与截面轴力和弯矩的关系,利用增量迭代方法,建立了带初挠度管形杆件极限轴压承载能力和后屈曲状态的计算程序,并在数值分析的基础上,考察了极限承载力的若干影响因素。 The relationship between elastic-plastic bending curvature,the axial force and bending moment of a tubular compressive column has been reviewed. An incremen tal-iterativc method has been employed to assess the ultimate axial loading and simulate the procedure of post-buckling of an out-ofstraight column. Some factors which influence the ultimate loading have been examined-by numerical analysis.
