MODELLING AND SIMULATION OF BUILDING EVACUABILITY IN ULTRA HIGH-RISE BUILDINGS

摘要

Although various codes of practices for building design, which control the safety use of the building, are enforced for individual components of buildings, such as staircases geometry, they may not offer an adequate measure for securing successful evacuation. Therefore, a model that can simulate the evacuation pattern of the occupants can facilitate the assessment of the effectiveness of the exit routes in a building. This paper develops a system dynamic model to analyze the interrelationship amongst the variables affecting evacuees in a building under emergency situation, and the computer software, ITHINK, is used to simulate the model.
