摘要
建立了考虑构件初弯曲的单层单跨钢框架计算模型,对不同初弯曲度下结构的位移、内力进行一阶和二阶分析,得出构件初弯曲对钢框架受力性能影响的一般性规律.
In this paper, some models of single layer-spaned steel frame with initial bending of members are established. Through the first and second order analysis on displacement and internal force of structure in the difference-defect degree, the universalizable disciplinarian of performance influence of original bend on steel frame has been gotten.
