As the market of steel building is increasing by the high quality, high speed construction and high strength then the ordinary construction materials, the possible risk of progressive collapse of steel building at the fire condition is going up gradually for the more increased combustible materials. The fire resistance of steel building has been evaluated by fire tests, but recently the performance based fire engineering make it easy to evaluate that of steel building using not only various engineering techniques but also fire science. The fire resistance of structural elements adopted at the steel building can be evaluated by the comparison between limit temperature that is at which the structural failure occurred according to high temperature of the structural element and maximum surface temperature of structural element by the application of heat transfer analysis. To establish the limit temperature for the structural steel(SS 400) and structural marine(SM 490) the tensile tests at high temperature were conducted and the comparison among the limit temperature references from abroad and the results from full-scale fire test of H-section column having 4 types loadings at the aspect of load ratio.
At this paper, the limit temperature equations from two kinds of steel specimens are very similar with that of abroad and the load ratio from coupon tests can be applied to real column element at the range of below 0.5. For more reliability, the comparison between the limit temperature got the limit state design and allowable working stress design and then the values from beam is needed.
