Abstract

This paper aims to experimentally investigate the fire resistance of U-shaped hybrid composite beams protected by spay and paint insulations. Subjected to two and three hours of the Standard ISO fire, the flexural performance of 4.4m beams with/without imposed loadings was examined with respect to failure criteria such as deflection and deflection rate of the mid-span and temperatures measured in the steel section. The results demonstrated that the proposed configuration of the composite beam is able to achieve a very competitive 3-hour fire resistance rating in economical aspects.
