摘　　要：在L形截面钢柱的弯扭屈曲一般性相关方程和轴心受压实用计算研究的基础上,对L形截面钢柱压弯组合承载力实用计算方法进行研究,化简L形截面柱弯扭屈曲一般性相关方程,考虑柱缺陷影响,用梁柱理论分析得出L形截面柱压弯组合实用设计计算公式,并通过几组L形截面柱偏心受压承载力试验,验证了计算公式。Based on the general equations of torsional-flexural interactive buckling and the axial compression for the steel abnormity-section columns, the applied calculation method of load-carrying capacity for the abnormity-section steel columns subjected to both bending and longitudinal compression is researched; simplifications have been made to the general equations of torsional-flexural interactive buckling. Considering the influence of column initial imperfection, by analyzing beam-column theory, the applied calculation formula for steel abnormity-section columns subjected to both bending and longitudinal compression is obtained. Finally, several groups of experiment about bearing capacity of L-section column under eccentricity compression have been done to testify the analysis formula.
