Abstract
When the pressurization system that uses difference of pressure for smoke control is designed, the factors influencing on the pressure field in building should be applied to design process and the stack effect is one of the main factors. Numerical analysis based on network model in 20-story building is carried out to analyze the pressurization system of smoke control in consideration of stack effect. Calculations are conducted for three conditions, that is, stack effect only, pressurization only and stack effect plus pressurization. Results including the detailed pressure field and flow rate at each floor are represented and the stack effect are effectively visualized. Meanwhile, the pressure of stairwell is increased as much as the summation of the stack effect and pressurization, and the problem induced by rise of pressure is pointed out.
