Behaviour of Composite Plate Girders With Partial Interaction

Abstract

Abstract. This paper is concerned with the behaviour and strength of composite plate girders in which, the interaction between the steel plate girder and concrete slab is partial. Based on curvature compatibility principle, an approximate method is proposed from which, the shear capacity and deflection at any given load may be determined. The tension field action developed in web panels at the post-buckling stage is incorporated in the solutions. From the results obtained by using the proposed method, it is found that the flexural stiffness and failure load drop with decrease in degree of interaction. Comparisons are made between the results obtained through the proposed method and the corresponding ones from finite element analysis. A satisfactory correlation between the results in terms of behaviour and strength establishes the accuracy of the proposed method. Keywords: composite plate girders, partial interaction, ultimate load, flexural behaviour, finite element method.

Study on Shear Connection of Bridge Steel Truss and Concrete Slab Deck

“…Recently new important studies concerning relevant parameters of steel truss chords, concrete slabs and shear connection in composite truss bridges were published (Bouchair et al 2012;Bujnak et al 2013). Other papers substantial for the following studies cover behaviour of shear connectors (Leon 2005;Mirza, Uy 2010;Faggiano et al 2009), complete composite trusses (Marcinkowski, Berkowski 1997;Mujagic et al 2010;Jung et al 2010) and various design aspects (Kravanja, Silih 2003;Szmigiera 2007;Yatim et al 2013).…”
