Abstract
This paper considers the time-varying behavior of composite steel-concrete beams with rigid or flexible connections under service loads. The age-adjusted effective modulus approach is used with evaluating the aging coefficient “χ” in absence of connection and characterized by a theoretical point of view. For a simplified expression to evaluate “χ” and for an easy method to implement, a closed-form solution in the hypothesis of rigid connections and uncracked concrete is proposed. The method is verified by comparing with the results of another finite element model.
