| Abstract: | The long-term analysis of continuous prestressed composite steel-concrete beams is presented. Referring to beams with thin slabs, the problem is solved in the viscoelastic domain by using a feasible algebraic formulation for the concrete creep constitutive law. In this way simple moment-rotation relationships, very useful for design, can be deduced. A case study considers the basic aspects of the problem, in particular the different structural responses to external loads and to prestressing. |
