Abstract

One of the most important component in performance-based design is tenability analysis study in a compartment. What it means by tenability analysis in this study is by getting the Available Safe Egress Time (ASET) based on several tenability criteria parameters namely Fractional Effective Dose (FED) for gases and thermal, smoke layer and visibility. To perform the tenability a nalysis; (1) selection and measurement of place of study i .e. two different room size in Faculty of Engineering, Universiti Putra Malaysia, (2) conduct fire load energy density survey at the place of study, (3) simulate probabilistic zone model simulation using B-RISK design fire tool; and finally (4) the tenability analysis itself. As a conclusion from the work, the values for each tenability criteria and results from B-RI SK simulations suggest that the ideal time taken for Toxicity (FED Gases) ≤ 60s, Heat Transfer (FED Thermal) ≤ 60s, and Smoke Layer Height ≤ 30s. Thus, the ASET for both office layouts are set at 30s due to the shortest time to reach tenability criteria.
