Elastic analysis of composite beams and beams retrofitted with FRP laminates with generalized end conditions

The elastic analysis of composite concrete-steel beams and beams retrofitted with FRP laminates is presented in detail. The proposed method and corresponding equations allow the analysis of these beams with generalized end conditions subjected to any transversal loads (concentrated and distributed forces and moments) including the simultaneous effects of shear, bending and axial deformations of each component and connecting material along its span. Three comprehensive examples are presented and the calculated results are compared with those obtained and reported by other researchers showing the efficiency and accuracy of the proposed method and corresponding equations.
