Engineering Simulation of Smoke Extraction Design in Atrium Fires of Student Union

Atrium of student union is a typical crowded place, it is difficult to achieve within the fire and smoke-protect separation. Once smoke entered, the security evacuation of personnel was threatened by rapidly spread smoke. In this paper, the atrium smoke exhaust design was researched, first introduces the method of smoke control in atrium buildings, research Smoke control system design theory with engineering examples, using FDS for atrium smoke control the numerical simulation, calculate a variety of exhaust design simulation results was calculated, enhanced the scientific and economy of smoke design through comparing.
