FE modelling of semi-rigid flush end plate joints with concrete-filled steel tubular columns

Abstract

A semi-rigid beam-to-column composite blind bolted connection is modelled using ABAQUS software. The composite beam is connected to the concrete-filled square column using blind bolts, and the model simulates a connection in hogging bending moment. Partial shear connection is considered, as well as the non-linear material properties of all constitutive components. All connection components were taken as roughly the same size as used in the experiments against which the method is calibrated, and the model does not need recourse to empirical push test data. The technique can be used to model connections easily, resulting in rapid and reliable solutions. © 2013 Taylor & Francis Group, London, UK.
