In this study, a general linear one-dimensional finite element beam model is developed for the analysis of the three layer composite steel- concrete- steel beams which are a special case of the multi-layer
Connectors, concrete layer thickness, plate thickness, type of loading and concrete compressive strength composite beams. The model is based on partial interaction theory of composite beams where the flexibility of shear connectors is allowed. A program is constructed using VISUAL BASIC language to analyze this type of beams. Numerical applications are presented to demonstrate the validity and applicability of the present method. A parametric study is carried out to demonstrate the effect of some parameters including the variation of shear stiffness of shear on the behaviour of three-layer composite beams. The results of
the proposed programmed model shows a good agreement with those obtained by finite elements method using ANSYS program (Release 11, 2007. The models used in ANSYS program are shell element, brick element and combine element to simulate the behaviour of steel plates, concrete part and shear connectors respectively

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