Abstract

In this paper, a layered 4-node 24-degree of freedom rectangular composite plate element is constructed based on a recently developed layered rectangular plate element for steel reinforced concrete slabs and Timoshenko's composite beam functions, and is then used for nonlinear finite element analysis of FRP-strengthened concrete slabs. The cross section of the element is composed of a series of concrete layers, steel layers smeared from steel re-bars and FRP layers, which are used to strengthen the existing concrete slabs. Both geometric nonlinearity of the slabs and material nonlinearity of the concrete are accounted for in the model to provide accurate prediction of the structural behavior. Full bond is assumed between FRP layer, steel reinforcement and concrete. The proposed numerical model is validated against available numerical and experimental results for a numerical example and then is used to analyze the nonlinear structural behavior of FRP-strengthened concrete slabs with different types of FRPs including CFRP, GFRP and Basalt fibers.
