INVESTIGATION OF THE EFFECTS ON THE SHEAR CONNECTION OF COMPOSITE BEAMS UNDER VARIOUS FIRE EXPOSURE

The paper discusses the development of a parametric finite element model for transient calculation of single span beams using standard fire curve as well as natural fire curves. The application of various advanced fire models leads to different natural fire curves depending on the fire loads. The effects of thermal loads on the composite joint are discussed. A finite element model is used to calculate the resulting slip of the composite joint and the resistance of a composite beam at different temperature-time curves with focus to the shear connections.     «
