Evaluation of the increased load bearing capacity of steel beams strengthened with pre-stressed FRP laminates by S. Bennati, D. Colonna, P.S. Valvo

“…We analyse the problem of a simply supported steel beam subjected to uniformly distributed load, strengthened with a pre-stressed fibre-reinforced polymer (FRP) laminate. We assume that the laminate is first put into tension, then bonded to the beam bottom surface, and finally fixed at both its ends by suitable connections. …”
