摘要
热轧及焊接钢梁同时承受双向弯曲和扭转作用的整体稳定计算,现行钢结构设计规范还未有规定。根据已有文献的试验和分析结果,结合现行《钢结构设计规范》(GB50017-2003)和《冷弯薄壁型钢结构技术规范》(GB50018-2002),提出双向弯曲和扭转同时作用下H形和槽形热轧及焊接钢梁的整体稳定验算方法,可为工程实践及相关研究参考。
In the current Chinese code of steel structures there are no any relevant rules for checking the stability of hot-rolled and welded girders under biaxial bending and torsion. The method for checking the general stability of hot-rolled and welded H-section or channel beams or girders under biaxial bending and torsion is proposed by analyzing existing experimental results in combination with the two current codes for steel structures, i. e. GB 50017--2003 and GB 50018--2002 ,which can be referenced by engineering practice and relative research.
