对单层工业厂房中常用的二跨、三跨连续冷弯簿壁槽钢截面墙梁的扭转问题进行了精确的理论分析。
This paper presents precise analysis on wall girder torsion of cold bend thin-section steel channel of 2 or 3 continuous bays commonly used.
表面处理形式、状态；支撑梁的截面尺寸和位置，槽钢的开口方向。
The size and position of the cross section of support beam, the opening direction of beam channel.
因此，对厚壁双冷弯槽钢焊接组合截面构件而言，确定其稳定承载力时应考虑焊接残余应力和冷弯残余应力的共同影响。
So for thick-walled double channels with welding composite section, the combined effects of the cold-formed and welding residual stresses shall be considered to assure the stability bearing capacity.
