With its complex type, it is a level-1 high-rise building. The fire protection system of this building mainly consists of fire hydrant, fire extinguisher system, the automatic sprinkling system and smoke control design. According to the relevant norms and building characteristics, appropriate fire-fighting systems are applied, which include indoor fire hydrant system, closed automatically sprinkling system, mechanical pressurization system, natural smoke exhaust and mechanical smoke exhaust system. The mechanical pressurization system, which is set up in each staircase and the second staircase, is applied to discharge smoke. It shares the front room with the fire lift so as to provide fire evacuation routes and shelter from the flue gas interference in the high-rise building. The fan model is determined through the calculation of air flow, duct cross-sectional area, resistance, etc. There are mainly two ways to discharge smoke, namely, natural smoke exhaust and mechanical smoke exhaust. When the fire breaks out smoke can be discharged in time to provide convenience for the evacuation and rescue. Through the division of the smoke partition and calculation of window area, we can get a fact that most of t
