Influence of the Degree of Shear Connection on the Load Carrying Capacity of a Composite Beam in Fire

This paper discusses the influence of elevated temperatures on the partial connection theory of composite beams with headed stud shear connectors. The load carrying behaviour of headed stud shear connectors in fire situation and its influence on the degree of shear connection of the composite beam is elaborated. Furthermore, the influence of the degree of shear connection on the load carrying behaviour of a single span composite beam is shown. Results suggest, that the degree of shear connection has only influence on the load carrying capacity of composite beams at ambient temperature, at elevated temperatures the softening of the steel section due to the rising temperature is the predominant factor.     «
