| 摘 要： | 应用有限元程序分析了钢－混凝土组合板的温度场。采用数值算法计算了组合板的耐火极限，同时分析了影响组合板耐火极限的参数。结果表明：由于混凝土的吸热作用，组合板的耐火性能要优于钢结构；随着板厚的增加，混凝土强度的提高，板的耐火极限增加；随着含钢率的增加耐火极限降低。温度场和耐火极限的计算结果得到了有关试验数据的验证，两者吻合较好。最后本文对组合板的防火设计进行了研究，并对防火保护层厚度进行了计算。

| Abstract: | In this paper,finite Element method is applied to calculate the temperature field of two kinds of composite slab. Fire resistance of composite slab has been calculated using a kind of numeric method. Also, factors related to the fire-resistance behavior are discussed. The calculating result has a good agreement with that of test. At last fire proof of composite slab has been analyzed in this paper. |
