In Taiwan, the fire code is prescriptive in nature and is inappropriate to be utilized in buildings with large spaces and atria, where performance-based fire safety design method is applied. It is the goal of this dissertation to develop a design guide for this application. Through literature survey and theoretical analysis, the important parameters were induced, including: plume transport time lag, ceiling jet transport time lag, smoke entrainment rate, mechanical and natural ventilation rate. To predict smoke behavior and descending rate accurately, algebraic equations and field model were both used to calculate and compare with experimental result so that its applicability can be evaluated. Furthermore, a full-scale experiment has been conducted in the USTC campus to validate that the field model can predict the smoke behavior and descending rate accurately. Finally, the calculation models developed in this study were compiled into a guideline for fire engineering performance-based designs. Design examples were also demonstrated to explain its procedure in engineering application.

Recently, several major incidents occurred in worldwide metro and subway systems due to inadequate or inappropriate emergency procedures. In this study, the traditional and innovative metro underground stations were analyzed utilizity the CFAST and FDS computer program. A comparative study has been conducted to evaluate the smoke descending rate, and temperature distribution, etc with addressable zoned smoke control system. Dynamic egress analysis was followed to validate the NFPA 130 which was taken as the design guidelines to evaluate the evacuation time using SIMULEX program. Finally, the smoke management design and egress system was integrated, which warrants its qpplication in actual engineering designs.
