摘　　要：中国《门式刚架轻型房屋钢结构技术规范》(GB 51022-2015)在冷弯薄壁型钢墙梁强度计算中,忽略弯扭双力矩以及墙梁和墙板自重的影响.上述规范在该计算问题方面与现行的中国《冷弯薄壁型钢结构技术规范》(GB 50018-2002)存在明显的差别.本文运用理论分析和算例研究方法,对上述问题开展分析研究,指出相关规范中存在的不足,并提出相应建议,可为有关设计计算提供参考.In China’s“Technical Code for Steel Structure of Light-weight Building with Gabled Frames”(GB 51022-2015),the calculation of the strength of cold-formed thin-walled steel wall beams,the influence of the double moments of bending and torsion and the weight of wall beams and wall panels are ignored.There are obvious differences between the above code and the current Chinese“Technical Code for Cold-formed Thin Walled Steel Structures”(GB 50018-2002).In this paper,theoretical analysis and case study methods are used to analyze and study the above problems.This paper points out the shortcomings of the code and puts forward corresponding suggestions,which can provide references for related design calculations.
