Modelización de vigas mixtas con interacción imperfecta

In most composite beams, the concrete and steel connection is flexible to some extent. For this reason, a relative slip always appears at the interface. This slip is of primary importance because it affects both the deflections and the stresses in the beam. To simulate this phenomenon, a two-dimensional finite element based on frame elements model is proposed. The main advantage of this model is its easy interpretation of the results and its applicability on design practice. To validate the accuracy of the proposed model, this has been verified against those results obtained by analytical equations available in the literature for different loading cases.Peer Reviewe
