In this study, loaded fire resistance tests for a simple supported small-scale roof member specimen using a corrugated steel thin plate were conducted to clarify the basic fire resistance performance under transient state condition. The cross-sectional shape and distributed loads were used as the test parameters, and the collapse temperatures were examined. According to the test results, it was clarified that the corrugated steel plate specimens possessed the high load-bearing capacities at high temperature ≥650℃.
