摘要
本文利用有侧移的轴心受压柱两端抗弯约束常数之间的关系式求解了单层厂房阶形柱的计算长度系数,并给出了单阶柱和双阶柱下段计算长度系数的实用计算公式。
In this paper, a relation between the end bending restraint constants of theunbraced concentrically loaded column is given. Using this relation, the equations ofthe effective length factors of the single and double stepped columns of the plane of thetransverse frame are developed. The numerical values of these factors are given in thespecification for design of steel structures GBJ17-88. For design purpose, practicalformulas of the effective length factors of stepped columns are recommended.
