Fire performance of hollowcore floor systems in New Zealand

摘要: The 2006 version of the New Zealand Concrete Standard NZS3101 has introduced two new details for connection precast and prestressed hollowcore floor units to supporting reinforced concrete beams. Although these amended have been experimentally proved yield better seismic performance building, concerns about their in fire still remain. A simplified novel approach model way action slabs with topping is established. This paper analytically investigates connected moment resisting building frames according old practice improved recommended using finite element tool SAFIR. simulation results show that rigid connections between systems perimeter beams provide resistance than rotationally flexible connections.
