摘要

轴向力对具有初弯曲的杆(管)柱变形影响很大。对此,本文分析了现有的杆(管)柱变形计算方法,并指出其不足。提出根据能量守恒换算一当量横向集中力代替初弯曲影响。

Abstract

Axial force has a great effect on deformation of rod or tubing with initial bending stress. For this reason,this paper analyses the problems of existing calculation method of deformation of red or tubing,presents a new methed to calculate deformation of rod or tubing by taking place of initial bending stress with equivalent lateral concentrated stress on the basis of the law of conservation of energy.
