摘　　要：火灾高温对结构材料力学性能有显著影响,会导致结构发生破坏,甚至整体倒塌。随着现代建筑技术的发展,空间结构的抗火性能研究越来越受到学术界和工程师们的重视。本文介绍了结构抗火研究的理论基础和相关概念;综述了结构抗火的研究状况;阐述了近年来空间结构抗火研究的进展情况;探讨了空间结构抗火研究存在的主要问题;对空间结构抗火研究趋势进行了展望,提出了目前空间结构抗火研究亟待解决的关键问题。Fire disasters take greatly effects on mechanical properties of structural materials, which results in damage of members in buildings or overall collapse of structures. With the development of modern constructional technique, more attention on the fire-resistance of space structures is paid by academics and engineers. The theoretical basis and concepts of fire-resistance of structures are introduced firstly, and then the advances on structures and fire resistance of space structures are introduced. Meanwhile the difficulties and the developing of the research on fire-resistance of space structures are concluded, and the urgent problems on fire-resistance of such structures which need further research are presented.
