薄壁槽钢受压承载力计算的有效宽厚比法

Bearing Capacity Calculation for Channel Sections in Press by the Method of the Effective Ratio of Width to Thickness

介绍一种考虑薄壁槽钢受压局部屈曲后强度的有效宽厚比法. 并在槽形截面腹板非均匀受压的屈曲后强度分析的基础上，对腹板及翼缘的有效宽厚比进行了列表计算，以供修订规范及设计计算参考.

Introducing the method of effective ratio of width to thickness by considering post buckling strength of channel sections in press. Based on theoretical analysis of the post buckling strength of channel sections under non-uniform compression in its webs, the effective ratio of width to thickness about the webs as well as flanges were presented in the tables .The tables are useful for modifying the standards as well as for reference in calculation and design.
