博士 === 國立中山大學 === 機械工程學系研究所 === 89 === 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.
