组合结构的耐火性能和抗火设计原理研究是工程界所关注的热点问题。该文简要介绍了国内外研究者们在组合板、组合梁、组合柱等结构构件以及结构节点、框架和结构体系耐火性能方面取得的部分研究结果,归纳了组合结构在火灾下(后)的工作机理和抗火设计方法及耐火性能研究方面的部分新进展。该文最后对组合结构抗火研究领域需进一步开展的工作进行了探讨和展望。
The research on fire-endurance performance and fire-resistance design of composite structures is one of the hot topics in structural engineering. This paper briefly summarizes and reviews some of the recent progress on the fire performance of composite slabs, composite beams, composite columns, beam-column connections, frames and structural system. Finally, A number of issues need to be addressed on the fire performance of composite structures are identified and discussed.
