Abstract
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
