Results and analysis of a large-scale fire test on a multi-bay composite steel-frame floor system

摘要

Purpose - This paper aims to facilitate verification of computer modelling techniques for complex structures exposed to fire and to test the effect of some steel beams being left unprotected. Design/methodology/approach - This paper describes a fire test conducted on a large-scale structure representing four corner bays of a typical multi-storey steel-frame office building. Findings - A new and unexpected mode of damage occurred. Originality/value - The test results indicate that an alternate reinforcement detail should be used in combination with unprotected beams.
