The evaluation of the ultimate bending moments of the fire exposed composite floor slab should be contained the restraint of thermal flexural strain. Imposing pure bending on the specimen that have fire protected offset at both ends is the handy experimental method for the evaluation of ultimate bending moments, particulaly for the connection on the supporting beam. This paper is on the estimation of the amount of the thermal flexural restraint of the thermal deflection just before the loading. This estimated amounts is calculated and compared with the results of experiment. The accordance is fatly good. From this estimation, the reason of the validity for using the value of negative ultimate bending moment obtained from this pure bending experiment becomes clear.
