An Analytical Model of Simply Supported Steel-Concrete Composite Beam With Bi-Linear Behavior of the Shear Connection Including Ductility: Formulation and Comparison With Numerical Results
Year: 2025
Type: article
Abstract: An analytical model of simply-supported composite beams is described. A bi-linear law of the shear flow-slip behavior of the shear connection is considered. The influence of the plastic hardening and ductility of the shear connection are included in the model. A formula to predict the end-slip of a generic simply-supported composite beam is derived. The model includes the cases of partial and full shear connection and of elastic and plastic design of the shear connection. The analytical model predictions are compared and checked against the results of a one-dimensional numerical model of composite beam including non-linearity. The comparison reveals a substantial agreement between the novel analytical formulas and the numerical model.
