3D BASED SMOKE FIRE EMISSION AND EMERGENCY EVACUATION SIMULATION IN HIGH-RISE BUILDINGS

Abstract

Abstract. High-rise buildings, with high number of population, have always been among the concerns discussed in urban crisis management. One of the crucial aspects of high-rise buildings is having a proper and timely action plan for evacuation in the case of emergencies such as fires. The spread and progression of fire smoke in high-rise buildings are affected by the architectural design of the building, and having a three-dimensional (3D) model of high-rise buildings can play key role in damage reduction in such cases. This paper, first presents a method for 3D smoke emission based on utilizing 2D cadastral data to generate a 3D model of the buildings. Then, in step of smoke fire emission simulation, the influence of different smoke movement paths such as the entrance/exit doors, windows, smoke barrier, stairs, and elevators, are examined in different scenarios. Next, the emergency evacuation of occupancies with different behavioral and physical characteristics is simulated. The results indicate that 2D cadastral data of apartments can be employed as a suitable source to create 3D models of high-rise buildings, and allows to examine the emergency evacuation of residents by including the smoke simulation spread in the building.
