![]() ![]() Currently available guidance from standard practice, egress modeling, codes and the research literature, is too general to provide much help to persons charged with the responsibility of where groups of occupants should be located given a fire scenario. This paper describes a decision model for managing the movement of building occupants during fire emergencies. The simulations of fire and smoke and coupled with simulation of evacuation have demonstrated that although there are adequate exits designated according to fire requirements, the impact of the geometry of atriums on the behavior of fire and smoke have significant effect on escape time especially for unfamiliar user of the premises. The results show that the buildings used as case study were designed according to Malaysian UBBL 1984 and Singapore Firecode, 2013 respectively provide relative safe means of escape. PyroSim, a crowd modelling software to conduct smoke study and Pathfinder to stimulate evacuation model of building in Malaysia and Singapore as comparative study. ![]() This research includes a scenario-based study on evacuation processes using two software i.e. This research aims at investigating the effectiveness of those provisions in public buildings during evacuation process involving massive crowd during emergencies. designated as means to allow occupants to escape within a safe period of time. As stipulated in the UBBL 1984, the means of escape provisions includes sufficient escape routes, travel distance, protection of escape routes, etc. The means of escape provisions is a critical requirement to safeguard occupants’ safety in fire especially in public buildings. Its prescriptive nature has made the requirements out dated from the viewpoint of current performance based approach in most developed countries. The Uniform Building By-law 1984 of Malaysia is the legal document governing fire safety requirements in buildings. ![]()
