碩士 === 元智大學 === 機械工程學系 === 91 === During early 1970, many old-fashioned five-story residential buildings were built in Taiwan. Unfortunately, these kinds of building usually are unsafe during a fire accident due to various reasons such as having only single stair egress route and lacking of fire alarm and extinguishing equipments, so they possess very high potential risk of human life losses during fire accidents. This thesis utilizes the numerical simulation method to analyze old-fashioned five-story one-egress buildings subject to various postulated fire accidents. We utilize CFAST software package of the zone model and PHOENICS computer code of field model to simulate the fire ignited at different positions and conditions. We divided into eight different models/136 cases to understand the spread trend of dense smoke and energy and their effects on people under different conditions of smoke controls/sprinkler systems. The impact of several fire protection equipments, strategies and engineering plans on the fire dynamics are reasonably evaluated.
