¡@¡@Recently due to the significant economic growth in Taiwan, buildings were constructed taller with usage diversified. However, the Building Code is difficult to cope with this rapid change and also sometimes with design negligence, fire accidents are not uncommon in this country. ¡@¡@Based on former experience, casualties occurred mainly due to the smoke hazard and inadequate time for egress. Therefore, quantitative assessment on these two items has become increasingly important, which is the main theme of this study. ¡@¡@During the design stage, a lot of constraints existed in adapting the local fire code, which is prescriptive in nature, especially in designing buildings with large spaces, atria, or malls. In that case, performance-based design was often attempted followed by quantitative risk assessment to validate its design effectiveness. ¡@¡@In this study, the ABRI Manual for Fire Risk assessment has been applied, followed by the F method for comparative study. The result indicated that both methods can be applied as reliable tools for fire risk assessment and warrants its application in engineering projects.
