Performance-based fire safety design was applied to a high-rise office building. Under each objective, required functins are specified associated with quantitative performance scale. The framework allows any combination of fire safety provisions as long as the required performance is achieved. Compared with prescriptive design method, the performance-based design method provides with open type office area, spatial efficiency (rentable ratio) and daily functionality. In case study, safety checking was made for evacuation safety and structural fire resistance. For the whole process of safety checking, simple hand-calculable formulae were adopted to give a quick estimate of the safety level. Through this case study, it was demonstrated that the performance design is practically feasible.
