Abstract

In recent years, in order to prevent the horizontal growth of cities, the idea of construcing high-rise buildings has been proposed. However, the occurrence of threats such as fire and terrorist attacks in high-rise and dense residential communities can cause devastating life and financial consequences, due to the slow down of the evacuation process of the residents. In this study, to provide a model of emergency evacuation, Qasr Ferdous residential community in Punak town of Zanjan, which has dense and high-rise buildings and a population of over 1200 people, has been selected as a case study. For this purpose, Pathfinder software has been used to simulate emergency evacuation. In this study, to reduce the evacuation time and the evacuation flow rate of the main door of the community, adding a new door to the community and changing the arrangement of parking lots and behavorial rules have been evaluated in 6 scenarios. The results of the analysis of these scenarios show that, changing the arrangement of parking lots and applying behavioral rules increases the flow rate by 8% at night and 15% at day. Moreover, adding a new door to the community, reduces the evacuation flow rate of the main door for night and day times by 12.3% and 2.8%, respectively, and also reduces the evacuation time by 31% and 34.5% for night and day time respectively.
