槽形截面压弯构件的等效轴压构件设计法

Selection of Beam-Column Channel Sections by Way of Equivalent Axial Compression Load

采用等效轴心受压荷载，按轴心受压构件设计承受轴力和弯曲荷载的槽形截面 双肢柱及单肢柱，使得槽形截面压弯构件的截面设计简便快速。算例表明，应用该方 法初选截面一般能较好地满足构件安全、经济、合理的要求。

Presented in this paper is a simple and quick method of designing beam-column channel sections by introducing equivalent axial compression load. The example shows that the section selection by this method is safe, economical and optimal.
