EXPOSED STEEL FRAMING ON HIGH RISE BUILDINGS

Abstract

Research program devoted to different fire protection methods, with emphasis on exposed steel; thermodynamic analysis led to conclusions that use of flame impingement shields is most efficient and effective method of protecting exterior steel spandrel girders from effects of fire inside building, and that for particular building simulated in fire test reported, shielded exterior spandrel girder web reached maximum temperature of 640 F during severe fire resulting from rapid burning of office fire load.
