Nonlinear Element for Concrete Beam Reinforced with Prestressed Hybrid C/G Sheet

The consolidation technology of prestressed hybrid C/G sheet takes full advantages of the initiative of the prestressed reinforcement and high strength of the novel composite material, which belongs to relatively advanced reinforcement strategies in reinforcement area. This paper derives nonlinear composite element and shell element to simulate concrete beam and the prestressed hybrid C/G sheet. Besides, the behaviors of nonlinear concrete beams are described by the Owen yielding criterion and the Hinton crushing criterion. Meanwhile, the three-dimensional prestressing effects of the composite C/G materials have been realized. This element can be used for the nonlinear analysis of concrete beam reinforced with prestressed hybrid C/G sheet.
