The structural behaviour of steel-concrete composite beams depends on the interaction between the steel beam and the concrete slab. Therefore, the connection largely influences the global behaviour of the beam and its modelling is a key issue in the analysis of these structures. An effective model requires the introduction of an explicit relationship between slip and interaction force given by each connector, which is strongly non-linear. In this paper, a numerical procedure that allows a reliable analysis of the structural behaviour of composite beams subjected to sagging moment due to short term loads, both in serviceability and ultimate state, is proposed.

Abstract
The structural behaviour of steel-concrete composite beams depends on the interaction between the steel beam and the concrete slab. Therefore, the connection largely influences the global behaviour of the beam and its modelling is a key issue in the analysis of these structures. An effective model requires the introduction of an explicit relationship between slip and interaction force given by each connector, which is strongly non-linear. In this paper, a numerical procedure that allows a reliable analysis of the structural behaviour of composite beams subjected to sagging moment due to short term loads, both in serviceability and ultimate state, is proposed.
