In kinematics it is assumed that each component of the cross-section is rigid in its own plane and only a relative slip can occur at the interface while the contact is preserved.

Abstract

In the past, the theories of composite beams with weak shear connection only dealt with the problem of bending on a symmetry plane. In this paper a beam model that also takes into account the other state of stress due to torsion and bending on a plane parallel to the connection is presented, in order to analyze the consequence of a flexible connection in these usual states of deformation. In kinematics it is assumed that each component of the cross-section is rigid in its own plane and only a relative slip can occur at the interface while the contact is preserved. The system of balance equations and relevant boundary conditions is established by the virtual work principle. Such a model is used for analyzing the torsion problem of a closed box section and some numerical results referring to a rectangular box section are presented.
