Abstract

This paper presents the behavior of simply supported concrete-steel composite beams with corrugated web under vertical loads using the commercial finite element (FE) software ANSYS. The three-dimensional (FE) model is used to simulate the overall flexural and shear behavior of simply supported composite beams with corrugated web subjected to vertical loads. This study covers: load deflection behavior and load strain curve. The reliability of the model is demonstrated by comparison with experimental results test carried out by author and others. Two identical composite beams with corrugated web were tested to failure under vertical loads. The comparison shows good agreement. A parametric study was undertaken using the validated model performed using finite element program. The parametric analysis was executed to study the effect of web thickness on the behavior of concrete-steel composite beam under vertical loads. The comparison between concrete-steel composite beam with corrugated and flat web was introduced in this paper. From this study, it can be concluded that, the corrugation in web increases the stiffness and ductility for composite beam. The increasing of corrugated web thickness increases the ultimate load and enhances the shear behavior of concrete-steel composite beam.
