Safety Evacuation in Building Engineering Design by Using Buildingexodus

The crowd motion and the evacuation process in a building engineering design were simulated by BuildingExodus tool when a combustible dust layer fire happened in this building. It focused on the effect of number of exits and population on time of evacuation, and evacuation efficiency of each exit by modeling the building. The simulation results were shown that the evacuation process would become much easier with the increase of exits and decrease of population. It was found that there was a linear relationship between number of population and time of evacuation. In the case study, the maximum allowable number of population was 2970. The evacuation efficiency of WN-1ST, FS2_1ST and DOOR7 was far better than FS_1ST and ES_1ST
