摘　　要：在建立室内火灾传热模型基础上 ,运用有限差分技术编制计算程序 ,以分析火灾下压型钢板 混凝土组合楼板在不同时刻的温度场 ,并得到了试验验证 。Heat transfer modes of compartment fire have been established in this paper.By using a combination of finite element and finite difference method,a computer program has been worked out to analyze the temperature distribution in composite deck slabs against fire,and it was validated by the test data.This program provides the basis for analysis of structures against fire as well.

关 键 词：压型钢板-混凝土组合楼板 火灾 温度场 有限元 传热模型 抗火性能
