Abstract

A three-eld mixed nite element is proposed for the non-linear analysis of composite beam with deformable shear connection. The formulation considers the non-linear behaviour of materials and shear connectors. The established mixed element is compared to the locking-free displacement element from which it derives and to a rened locking-free displacement element previously tested by the authors. In order to evaluate the way to better improve the solution in the non-linear range (three-eld mixed formulation or rened displacement formulation), numerical applications are performed using, as working example, a steel- oncrete cantilever, representing a di3cult test for composite beam elements.
