The scope was too broad to cover every area in hospital. The sprinkler system was chosen to be the first evaluation item for hospital by using Fire Dynamics Simulator (FDS). Sprinkler layout, Fire size, and its location had significant effects for sprinkler actuation. The sprinkler took longer to actuate when 500kW fire was under 30cm thick beam. The sprinkler was accelerated to activate, when 500kW fire was under a 30cm thick beam and the beam was 10cm or 20cm away from the ceiling. The beam effect was insignificant when the fire was 1500kW. If the fire origin was moved 1m horizontally away from the beam and there was no clearance between ceiling and beam, the sprinkler was hard to activate. There was no difference for sprinkler actuation time of 10cm or 20cm clearance between ceiling and beam. They are also the same response time as a free ceiling for the same fire size. 【key word】: performance-based design、CFD model、hospital
