摘要

> Problem statement: This study investigates the fire evacuation problem of the library building by using the Fire Dynamics Simulator with Evacuation (FDS+Evac.) programming. Approach: The assumption is made that the sprinkler system is installed in the building but the system is malfunction, which is considered as the worst case of the situation. The simulations are divided into 4 cases, which are case 1; the numbers of evacuating persons are 517 persons and the heat release rate is 5 MW, case 2; the numbers of evacuating persons are 517 persons and the heat release rate is 7 MW, case 3; the numbers of evacuating persons are 788 persons and the heat release rate is 5 MW and case 4; the numbers of evacuating persons are 788 persons and the heat release rate is 7 MW. Results: The results are shown that the 1st case and the 2nd case have the evacuation times of 8.63 and 8.81 min, respectively. There is no dead person found from both cases. For the 3rd and the last case, the evacuation times are 18.17 and 18.83 min, respectively. The 3rd case has 1 dead person and the last case has 18 dead persons, respectively. Conclusion: The number of evacuating person and a size of fire have a directly impact on the evacuating person. The reasons are the crowded situation of evacuation and a higher toxicity that is occurred. So, the stairway of the building has to be improved and changed to be the fire escape. This brings to the increasing in the capability of the evacuation.
