• 摘要: 为在建筑结构火灾反应分析中考虑实际火场特性，并简化火场分析模型与结构有限元分析模型之间的复杂对应关系，提出并建立了火场温度及对流辐射边界的热传导分析时空模型(STM)和基于时空模型的火场-结构联合分析方法。该方法根据火场模型计算出室内火场温度分布场以及对流辐射边界场离散数据，通过双向正交多项式进行拟合来得到不同时刻的构件边界连续时空模型，再通过时空模型进行热传导分析和热力耦合分析，从而实现火场-结构联合分析方法。在验证其合理性的基础上，通过ABAQUS子程序UTEMP和DFLUX实现其分析过程，并进行了北京某档案馆工程的应用分析，结果表明该方法可以较好地联合火场模拟与结构分析用于结构火灾安全评价。
