equivalent slenderness ratio
equivalent uniformly distributed live load

Equivalent slenderness ratio
换算长细比57
In active code for design of steel structures , axially compressed members are calculated not as torsional - flexural buckling but as flexural buckling with equivalent slenderness ratio , residual stress and initial geometry imperfection are also taken into account as flexural buckling
我国现行钢结构设计规范( gb50017 )采用换算长细比的方法将弯扭失稳等效为弯曲失稳，其残余应力和初始几何缺陷均按弯曲失稳考虑。
According to the elastic bucking theory this paper reviews and compares the calculations that such member bend around the reat axis and the hollow axis as well as bend with torsion around the hollow axis . here this paper presents a formula of calculating b used in with the h - shaped anglicizing element . meanwhile , this paper deduces out a formula of calculating b . by , which the member could be controlled to only buckle around the real axis
本文根据弹性屈曲理论对双肢格构式单轴对称缀板柱绕实轴、虚轴以及弯扭屈曲进行了计算分析和比较，提出了绕虚轴侧向屈曲的换算长细比_ ( oy ) = ( y ~ 2 + l ~ 2 ) ~ ( 1 / 2 )中的值用h计算单元指出的计算公式，同时推导出了单轴对称缀板柱只出现绕实轴弯曲屈曲的最小肢间间距b 。
