On the fire safety for internal voids in highrise buildings

Fire safety of the new internal voids design for highrise buildings in Hong Kong was studied by covering three areas: • Fire in a room adjacent to the internal void, including possibility of flashover and amount of smoke flowing out.• Spread of smoke from the fire level to adjacent levels.• Fire resistance provisions for windows. Fire models including application of computational fluid dynamics (CFD) are used for the analysis. CFD results indicated that there might be a potential fire hazard in this kind of design. Further studies should be carried out to investigate the problem
