摘　　要：本文介绍了约束钢柱抗火设计方法的研究进展和已有研究成果,包括火灾下整体结构的分析方法,火灾下约束钢柱的受力性能理论分析和试验研究,约束钢柱在火灾下的计算长度,约束钢柱的高等抗火设计方法和简化抗火设计方法等,并对需要进一步研究的问题给出了建议。A literature review and main progress on behaviour and design method of restrained steel column in fire is presented. The main focuses of the literature review are global framed structural analysis in fire,fire tests and parametric studies on restrained steel column,buckling length of restrained steel column under fire condition,advanced and simplified fireresistance design method for restrained steel column, and so on. The key problems on fire resistance design of restrained steel column needed further research are pointed out.
