Finite Element Anaylsis Of Composite Element For FRP Reinforced Concrete Slab By Using ANSYS

ABSTRACT In this paper, a nonlinear finite-element analyses have been carried out to investigate the behavior up to failure of simply supported composite steel-concrete beams with external pre stressing, in which a concrete slab is connected together with steel I-beam by means of headed stud shear connectors, subjected to symmetrically static loading. ANSYS computer program has been used to analyze the three dimensional model. This covers: load deflection behavior, strain in concrete, strain in steel beam and failure modes. The nonlinear material and geometrical analysis based on Incremental-Iterative load method, is adopted. Three models have been analyzed to verify its capability and efficiency. The results obtained by finite element solutions have shown good agreement with experimental results. The present study deals with the finite element modeling of control RC slabs and strengthened slabs with the help of ANSYS.ANSYS is software that is based on FEA method in which modeling of RC structures is done. In this study, a control slab was modeled and the results were analyzed and then strengthened slabs were modeled and analyzed. The results of the control and strengthened slabs were compared with the experimental results. It was observed that the results of the strengthened slabs are in close agreement with the experimental results.
