An Analysis of Evacuation under Fire Situation in Complex Shopping Center Using Evacuation Simulation Modeling

As the economies grow, a number of high-rise buildings and large complex shopping canters have been built in Korea. However, these buildings are huge and complex in their size and structure. Therefore, agents will face evacuation problems under the fire situation. Unless agents evacuate rapidly, they will suffer from the suffocation and poisoning to death. This paper analysed relevant to both human and structures evacuation factors through the agent-based model. The agents are classified for simulation modelling into three cases and four groups. Each case contains different number of agents and each of the four groups shows different levels of exit awareness. Also through the potential route plan of each group, analysed total evacuation time is analysed. As a result, it is found that human conflict is responsible for the total evacuation time as the conflict between the familiar and the unfamiliar occurs within the interior structure. Thus, the spatial environment factor that evacuation time of case best is 8’22” but other cases up to 60’. It is also an effective way for evacuees to be provided with optimized width of exits near high density area. To reach out further, future studies may implement other various factors such as toxic gases and transportation vulnerable.
