Abstract
As a part of the performance based design, egress modelling should be conducted to check whether the architectural design and plan phase of large-scale building can be safe in case of fire. However, an egress simulation has been used to create a fire/egress scenario without the formal guideline and standard. Therefore, the safety performance of building depends on user's own judgement. The purpose of this study is to establish the evaluation index on fire/egress scenario factors through AHP(Analytic Hierarchy Process) analysis. Prior to this, setting trend of creating fire/egress scenario was investigated in order to draw scenario factors. The survey result shows that different scenarios are set by users. Based on prior survey, specific factors are separated by fire/egress scenario and are stratified. To index stratified factors, second survey is conducted to establish objective data by experts, each evaluation index is set depending on survey results. As the results at this research, the highest index was risk factors (such as obstacle, smoke, bottleneck phenomenon and so on) and the door open & shut. On the other hand, the lowest index are egress safety zone and temperature difference between inside and outside in vertical space.
