In this study, the fire resistance performance of a simple support composite beam, which was sprayed with fire protection coatings, was evaluated. Primary valuables of the study are loading and unloading, shape of composite beam and metal lath of the web. The thickness of the fire protection coating to the three hour resistance is 40mm, but the fire resistance test was performed with 25mm coatings. The test result showed that TSC composit beams with 25mm fire protection coatings can resist on fire for three hours at the both loading and unloading tests. Average and maximum temperatures were less than 250oC and 310oC respectively, compared with the standard temperatures for fire
resistance on the loading and unloading tests.
