Abstract
A 15,000 seat indoors sports arena following the performance-based fire engineering design was analyzed in this paper. 3D CFD analysis using FDS software indicated that the original dome design was inefficient as a smoke reservoir and fails to provide a smoke-free escape route during evacuation. Therefore, the whole architectural design was modified with dome reshaped, and with mechanical fans and natural vents added, until the smoke-descending rate was controlled effectively. The egress simulation also pointed out several bottlenecks formed by evacuees, leading to relocation of staircases and facilities, until the evacuation time allowed is within the limit provided by the smoke management systems with some tolerances. The iterative design process proves itself a successful and effective procedure and is discussed in detail in this paper.
