Abstract
![CDATA[This paper addresses the issue of the deformations that occur in composite steel-concrete beams caused by creep and shrinkage of the concrete slab, and in which the effects of partial shear interaction (PI) at the interface between the slab and the steel joist are included. By making recourse to an algebraic representation of the viscoelastic response of the concrete, the formulation in this paper leads to the solution of the problem in closed form. The solution does not require a discretisation along the beam, but only one discretisation in the time domain, and the solution is generic in the sense that it may be applied for a variety of loading and restraint conditions. Specific solutions, that are validated against a numerical technique, are presented for a simply supported beam, an encastre beam and for a propped cantilever.]]
