A review on research of fire dynamics in high-rise buildings

Since serious fire occurred frequently in recent years, fire safety of high-rise building has attracted extensive attention. A National Basic Research Program （973 program） of China has been set up by Ministry of Science and Technology （MOST） of China in 2012 to meet the research requirements of fire safety in high-rise buildings. This paper reviews the current state of art of research on fire dynamics of high-rise buildings, including the up-to-date progress of this project. The following three subjects on fire dynamics of high-rise buildings are addressed in this review： the ejected flame and fire plume behavior over facade out of the compartment window, the flame spread behavior over facade thermal insulation materiMs, and the buoyancy-driven smoke transportation characteristics along long vertical channels in high-rise buildings. Prospective future works are discussed and summarized.

Editorial: Special subject on the mechanical behavior of fire dynamics in high-rise buildings

With rapid economic and social development in China, high-rise buildings have continuously sprung up since 2006. However, several big fire accidents in high-rise buildings such as the Beijing Television Cultural Center fire in 2009 and the Shanghai Jing＇an District fire in 2010 etc. have claimed people＇s lives and caused huge amounts of economic and property losses,

The Analysis of Human Behaviour and Evacuation in a Fire Situation in a Building for Higher Education

The paper presents the analysis of a human evacuation from a higher education building located in Iassy,Romania,by means of engineering techniques to approach fire safety.Because in Romania(as in other European countries)fire safety design of buildings is prescriptive and not performance-based,a fire safety engineering approach arouse great interest in many countries such as the U.S.A.,Australia,New Zealand,England,Sweden,Finland,etc.This paper is based on the assumption of starting a fire in the space of a hall for festivities,located on the ground floor of the building,near two human evacuation routes;We consider two building evacuation scenarios:two exits and,respectively,just one exit(assuming that the second would be accidentally blocked).

Agent-Based Evacuation Model Incorporating Fire Scene and Building Geometry

A comprehensive description of the key factors affecting evacuations at fire scenes is necessary for accurate simulations. An agent-based simulation model which incorporates the fire scene and the building geometry is developed using a fire dynamics simulator （FDS） based on the computational fluid dynamics and geographic information system （GIS） data to model the occupant response, The building entities are generated for FDS simulation while the spatial analysis on GIS data represents the occupant＇s knowledge of the building. The influence of the fire is based on a hazard assessment of the combustion products. The agent behavior and decisions are affected by environmental features and the fire field. A case study demonstrates that the evacuation model effectively simulates the coexistence and interactions of the major factors including occupants, building geometry, and fire disaster during the evacuation. The results can be used for the assessments of building designs regarding fire safety.
