Generalised Beam Theory for composite beams with longitudinal and transverse partial interaction

Abstract: This paper presents a Generalised Beam Theory formulation to study the partial interaction behaviour of two-layered prismatic steel–concrete composite beams. The novelty of the proposed approach is in its capacity to handle the deformability of the shear connections at the interface between the slab and steel beam in both the longitudinal and transverse directions in the evaluation of the deformation modes. This method falls within a category of cross-sectional analyses available in the literature for which a … Show more

“…The first improvements regard the connection system, for which the multidirectional behaviour was introduced into 1D beam models; among others, Gara et al [11] and Ranzi et al [12] developed finite elements for two-layered composite beams capable of accounting for the deformability of the slab-girder shear connection in the longitudinal and transverse-vertical directions. Partial interaction in both the longitudinal and transverse-lateral directions was instead introduced by Taig and Ranzi [13] in a very sophisticated model capable of capturing the behavior of elements such as bridge composite box girders, in which cross-section deformation occurs. Discrete connections were also considered by Nguyen et al [14] by considering friction arising at the interface of the two components in the contact areas.…”

“…The most recent and advanced models, in terms of enhanced kinematics, are those developed in the framework of the generalized beam theory and those denoted as higher order models. Taig and Ranzi [13] presented a two-layer composite beam model capable of capturing cross-sectional deformations and partial interaction in both the longitudinal and transverse directions by introducing a set of deformation modes derived by modal analysis of planar frames representing the cross sections. Similarly, Gonçalves and Camotim [29] presented a model able to capture the effects of cross-sectional deformation for a wide range of analyses including vibration and lateral-torsional-distortional buckling of composite cross sections typical for bridge applications.…”
