초록

In this study, the effect of thickness of sprayed fireproofing on temperature of main bars under fire test was investigated for high strength concrete member(column) prevented the spalling. The thicknesses of sprayed fireproofing were 0, 10, 20 and 30mm. Test was carried out according to ISO-KS standard temperature-time curve during 3hrs. Based on temperature results of main bars after 3hrs, it appears that the temperatures of the main coner bar are about 400$^{circ}C$ and 500$^{circ}C$, when the thicknesses of sprayed fireproofing are 5mm and 2mm, respectively.
