摘　　要：进行钢结构防火保护设计时首先应确定截面-材料综合系数,已有研究已给出该系数在不同火灾模型中的相似准则。通过建立实际火灾模型中防火保护层外表面温度序列数学模型,并结合该相似准则和标准火灾模型中该温度序列,构造MATLAB/Simulink仿真平台,计算任意火灾模型中的截面-材料综合系数。最后应用该模型设计常用t2(t为耐火时间)火灾模型的截面-材料综合系数作为示例进行分析。The section-material comprehensive coefficient should be firstly determined when design the fire-proof of steel structure,the similarity criterion for the coefficient in different fire models has been reported in some researches. Through building surface temperature sequence mathematical model for the fire-proof of an actual fire model,and combining with the similarity criterion and the temperature sequence in standard fire model,the MATLAB / Simulink simulation platform was constructed for solving the parameters in any fire modes,and finally,the section-material comprehensive coefficient of t2 fire model was applied into the design of the model and anlyzed.
