Investigation on Behavior of Castellated Composite Beams under Fire
This paper is to study the fire resistance of castellated composite beams.Based on experiment,a reasonable castellated composite beam model is established by using finite element software.The critical temperature of castellated composite beams influenced by hole opening ratio,hole pitch,width-thickness ratio of the web and stiffener have been analyzed.The result shows that stiffener has a great influence on the fire resistance of castellated composite beams,which can increase the critical temperature greatly.The width-thickness ratio of the web has some influence on the buckling behavior of castellated composite beams under fire condition.When width-thickness ratio is higher,the web is more prone to buckling failure.The hole opening ratio and hole pitch have a little influence on the fire resistance of castellated composite beams.
