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

摘要

A semi-rigid beam-to-column composite blind bolted connection is modelled using ABAQUSrnsoftware. The composite beam is connected to the concrete-filled square column using blind bolts, and thernmodel simulates a connection in hogging bending moment. Partial shear connection is considered, as well as thernnon-linear material properties of all constitutive components. All connection components were taken as roughlyrnthe same size as used in the experiments against which the method is calibrated, and the model does not needrnrecourse to empirical push test data. The technique can be used to model connections easily, resulting in rapidrnand reliable solutions.
