| Abstract: | 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. |
