| 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。

| Abstract: | 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 bend ing and torsion. The method for checking the general stability of hot-rolled a nd welded H-section or channel beams or girders under biaxial bending and torsi on is proposed by analyzing existing experimental results in combination with th e two current codes for steel structures, i. e. GB 50017-2003 and GB 50018-2002 ,which can be referenced by engin... |
