These problems included a simple reinforced-concrete beam, a reinforced-concrete slab, and a composite steel girder with a partial concrete slab. Key words: ABAQUS, finite element, fiber reinforced polymer, reinforced concrete beam, nonlinear failure. In ABAQUS (2007), two main constitutive models are available for non-linear finite-element analysis of plain concrete. The increased of loads on existing reinforced concrete infrastructure and the lack of initial design and construction will induce flexural and shear failure. Simulation Finite element method was used to creating a 3D model of reinforced concrete column under load and exposed to high temperature in Abaqus. Distribution Statement No restrictions. The results from experimental tests and ABAQUS simulation were compared. VecTor2 is a nonlinear finite element analysis of two-dimensional reinforced concrete membrane structures subjected to quasi-static load conditions. precast concrete cladding panels, although the concept can also be applied to floor-to-floor high Finite Element Modeling of Reinforced Concrete Cladding Panels H.
