Abstract
Large spaces, such as warehouses where internal loads are stored, exhibit higher fire loads and faster fire growths than general fires. In addition, the volume of the internal load reduces the space required for the smoke to stay, thereby accelerating the decline in smoke height. To prevent fire hazards in such spaces, it is necessary to evaluate the fire risk during the design stage. However, it is difficult to evaluate various settings because the evaluation method using the existing computational fluid dynamics utilize considerable amount of time. In this study, an algorithm was developed to evaluate the internal loads by using formulas related to the existing fire risk assessment. The developed algorithm is designed to easily calculate the detection time of the detector, smoke fall time, and sprinkler operation time. This algorithm could be used to design an optimized fire protection system in the initial design stage.
