The authors have previously proposed a non-linear load deformation relation model for predicting the elasto plastic behavior of the panel zone of steel beam to concrete-filled square steel tubular column connections. This model is based on superposition of the tri-linear relation for the steel tube and the infill concrete. This research verifies the analytical model by comparison with experiment results of the various experimental parameters. The analytical results agree approximately with the experimental results up to a large shear deformation. Moreover, a simple model based on a tri-linear relation is proposed for the panel zone, which produces the same result as the non-linear relation model by comparison with the experiment result.
