摘要
采用有限元方法,对火灾下压型钢板-混凝土组合楼板的温度场进行了分析,得到了瞬态温度场分布云图及温度随时间变化的曲线,并与试验结果进行比较,二者吻合较好.表明所建立的计算模型合理、模拟方法正确、可行;同时比较了两个不同仿真模型的计算结果,从而得出最佳计算模型,为计算火灾下构件温度场提供了实用的方法;对研究组合楼板抗火性能具有重要意义.
The temperature distribution in composite deck slabs under fire is analyzed by using Finite element method. The transient temperature contours and curves varying with time acquired from numerical simulation and experiment are quite i- dentical. It is showed that the calculation model is reasonable and the method is correct and feasible. Meanwhile, the optimal calculation model based upon the comparison of calculation results of two different simulative models is obtained; a practical approach is developed for the temperature distribution of member under fire. It has a great significance to the performance studying of composite slab against fire.
