Abstract

Abstract

In order to study the fire resistance of castellated composite beams, the fire resistance tests of castellated composite beams and composite beams were carried out. The performance of castellated composite beams at high temperature was studied. The effects of web opening and opening shape on the performance of composite beams under high temperature action were compared and analyzed. The results showed that the castellated composite beam was destroyed due to the flexural-torsional buckling of web under high temperature. Openings had a great influence on the temperature distribution of beams under fire, which significantly reduced the fire resistance limit of beams. The shape of openings had little effect on the fire resistance of castellated composite beams. The stability of circular castellated composite beams with openings was better than that of regular hexagonal castellated composite beams at high temperature.
