摘　　要：结构抗火分析是涉及到建筑结构和消防安全等方面的重点难点问题，火灾高温对结构有显著影响，火灾极易造成结构损伤、破坏甚至倒塌。随着我国基本建设的发展，结构抗火问题凸显其重要性。由于建筑物的规模和尺度都在不断加大，大幅度增加了火灾扑救的难度，这使得在加强结构抗火方面面临很多问题亟需解决。本文简要论述了近年来结构抗火研究的现状，指出了目前抗火研究尚需解决的关键技术难题，特别是基于实际火灾发展模型的结构抗火分析以及消防实践中高性能混凝土淬火效应导致的爆裂两个突出的问题。Structure fire resistance analysis is an important problem in structure design and fire safety of building. High temperature which can cause damage and collapse of building has great influence on structure. With the rapid progress of the construction and infrastructure, significance of fire-resistance of structure is emerging. Many problems should be solved immediately because of difficulties of fire-fighting due to increasing of building scales. In this paper, development of structure fire resistance research is introduced briefly, and the technological difficulties which need to be solved imminently are presented. The key problems such as structure fire resistance analysis based on real fire model and water quenching effect of high performance concrete in fire fighting process needed further research.
