摘　　要：阐述了钢桁架结构抗火研究的背景与意义,分析了火灾高温下钢桁架结构的内力重分布、构件变形及结构破坏特征,论述了钢桁架结构抗火研究的现状及进展,指出了钢桁架结构抗火研究尚存在的问题,并提出了相应的建议措施。The background and significance of the fire resistance performance for steal truss structure was introduced briefly, and the internal force redistribution, component deformation, breakage characteristics of the structures in fire were analysed further. Then, the status and progress of the investigation for fire-resistance of steel truss were discussed and summarized. Based on the above, some existen and some reasonable advices were
