This work deals with the behavior of structural continuous composite steelconcretebeams, which are widely used in building and bridge constructions. Thereforethe structural behavior of composite beams under negative moment is a significantsubject. However experimental tests in this field are very rare and information about theefficiency of shear connection when the slab is under tension are really few.In the present research, available experimental tests on composite steel-concretebeams under negative bending are theoretically analyzed using the finite elementsoftware ANSYS. ANSYS computer program is a large-scale multipurpose finiteelement program which may be used for solving several cases of engineering analyses.The proposed three dimensional model is able to simulate the overall flexuralbehavior of composite beams. This covers; load-deflection behavior, longitudinal slip atthe steel-concrete interface, and distribution of shear studs. The reliability of the modelis demonstrated by comparison with available experiment and alternative numericalanalysis which shows 9-10% difference.
