SHEAR PANEL COMPONENT IN THE VICINITY OF BEAM-COLUMN CONNECTIONS IN FIRE

摘要

This research is intended to predict the shear buckling of beam webs in the vicinity of beam-to-column connections in fire.A component-based analytical model, which simulates the behaviour of beam-web shear panels from the elastic stage to failure, has been created for elevated-temperature analysis.ABAQUS models have also been created to validate the component model over a range of geometries.Comparisons between the theoretical and FE models have shown that the proposed component model provides sufficient accuracy to be embodied in due course in global modelling of composite structures in fire.After sufficient validations have been carried out, the new component-based model will be implemented into the software Vulcanas a shear panel element adjacent to the existing connection element.
