| Abstract | ||
| This paper presents a nonlinear finite element computer program. ANSYS version 12.0 developed for the analysis of composite steel-concrete beam. A three-dimensional finite element (FE) model has been developed in this work. The analytical results of load-deflection response have been compared with available experimental tests. In general good agreement between the finite element solutions and experimental results have been obtained. Parametric studies have been carried out to investigate the effect of some important material and geometrical parameters. These parameters included the effect of shear connectors number, concrete grade, thickness to width ratio of concrete slab, the ultimate load for shear connector and effect of yield strength of Steel beam. It was found that, as the compressive strength of concrete increases from 20 MPa to 70 MPa the ultimate load increases by about 20% and also an increase in the thickness to width ratio (t/B) of concrete slab from 0.1 to 0.3 lead to increase in the ultimate load by about 43%. | ||
