Fire Protection Analysis of the Orfalea College of Business Building (#3)

摘要

A performance and prescriptive based analysis was performed on the Orfalea College of Business Building (#3) on Cal Poly’s Campus. The building was originally designed to meet the 1985 Uniform Building Code (UBC). The building’s original design and current existing condition will be examined. The business building will be evaluated using the California Building Code, California Fire Code, NFPA 101 Life Safety code and other relevant NFPA Codes. The fire protection systems will be separated and evaluated into systems by Egress Components, Fire Alarm and Detection, Water- Based Suppression and Structural Fire Protection. The combined interactions of the systems are evaluated in the performance analysis. The required safe egress time (RSET) and available safe egress time (ASET) are evaluated to determine if the fire safety goals are met. For this report the fire safety goal “To minimize firerelated injuries and prevent undue loss of life” is the primary focus (NFPA 101, 2012). Fire Dynamics Simulator (FDS) and Pathfinder were utilized to evaluate the performance of the building under fire scenarios. Using the fire safety goals and objectives, a set of performance criteria are established in order to determine if the ASET and margin of safety is sufficient. Prioritized recommendations and further research that needs to be under taken are discussed.
