摘要
本文对多高层支撑钢框架柱的计算长度问题作了阐述。在结构基本失稳形式分析的基础上,给出了确定支撑框架柱计算长度的计算简图与计算公式,为便于工程设计运用,在充分利用《钢结构设计规范》(GBJ 17—188)中纯框架柱计算长度系数表格的基础上,提出了确定支撑钢框架柱计算长度系数的近似计算公式。
The problem on calculating the effective length for a column in a braced steel frame it discussed in this paper.An analytical modcl.based on the analysis of basic instability configurations of frameworks,for calculating the effective length of an arbitrary braced frame column is proposed and formulated.For the convenience of practical application,a simplified approach to the estimation of the effective length values of columns employed in rigid-joint steel frames is also presented.
