Abstract
Analytical solutions based on general differential equations and finite element formulations for in-plane analysis of composite steel/concrete beams including the effects of partial interaction are presented in this study. The partial shear interaction, which happens as a result of having flexible shear connections, brings about lower flexural rigidities, particularly in hogging regions of the composite beams. The presented analytical solution can be used to calculate the in-plane critical stress resultants that may initiate the out-ofplane buckling of the steel joist. Unlike the published works, the current finite element model accommodates the partial shear interaction and general loading and end support conditions, and also accounts for the variation of beam's flexural rigidities in hogging and sagging regions. Numerical examples are provided to demonstrate the accuracy, efficiency and versatility of the derivations.
