为方便生活辅助设施在墙体中通过，常在低层轻钢住宅结构中采用开孔冷弯薄壁型钢柱作为承重构件形式。近年来，许多学者对冷弯薄壁型钢构件畸变屈曲稳定问题开展了大量的研究工作。目前关于开孔柱构件弹性畸变屈曲应力计算方法是柱构件稳定性能研究亟待解决的关键问题。本文采用有限元方法与有限条方法相结合的手段，提出了基于全截面厚度折减的有限条分析方法及适用于设计规范的弹性畸变屈曲应力计算公式。分析表明：提出的相关计算方法可以用于开孔柱构件弹性畸变屈曲应力的计算。

Cold‐formed thin‐walled steel columns are commonly provided with holes as bearing mem‐bers to accommodate auxiliaty living facilities crossing in the low‐rise lightweight steel residence struc‐ture .Study on the distortional buckling stability of cold‐formed thin‐walled steel members have wide‐ly been implemented in recent years by some researchers .The elastic distortional buckling stress cal‐culation method for open‐hole column is the key issues in stability problem of cold‐formed thin‐walled steel structural member .The design method of elastic distortional buckling combined with finite strip method and finite element method was proposed ,which contained finite strip method based on modif‐ying w hole cross‐section thickness and calculation formula in this study .It is show n that the proposed methods can be used for design specification .
