Numerical study of reinforced concrete beam subjected to simple bending

Abstract

    The article presents the numerical study dealing with the behavior and the real load bearing capacity of composite steel-concrete beam with several fully encased steel profiles in case no connection between the surfaces of steel profiles and surrounding concrete subjected to simple bending by Abaqus software. Especially identify the bearing capacity behavior of the composite steel-concrete beam while the materials were yielded until failure. Contents of the paper consist: descriptions of the structural composite steel-concrete beam, material behavior, schema, element types, numerical solution controls, as well as graphic user interfaces, auto-meshers, and sophisticated postprocessors and graphics to speed the analyses. It is expected that nonlinear FEM analysis can give more details on behavior as well as on shear and bending resistance mechanisms until failure of the composite steel-concrete beam. The specific purposes of the analysis to verify nonlinear FEM analysis can predict well specimen strength, maximum displacement, strain and stress distribution, slip distribution, crack pattern, failure modes.
