The effects of partial shear connection on composite steel-concrete beams subjected to combined flexure and torsion

Western Sydney University thesis: Doctoral thesis

Abstract

Composite steel-concrete construction has been widely used around the world. Techniques for the ultimate load analysis and design of composite steel-concrete beams are also well-established and solutions can be obtained with relative ease. However, beams under combined actions such as edge or curved in plan beams subjected to torsion and flexure can be difficult to ascertain their strengths and behaviour due to their complex stress state. These effects of combined actions are not currently addressed in the Australian Standard AS2327.1 (Standards Australia, 2003) or any their international codes. Therefore, this thesis will present two full-scale experimental series to investigate the behaviour of straight and curved in plan composite steel-concrete beams subjected to torsion and flexure with the influence of partial shear connection. Push-out and material tests were carried out to determine the material properties of each component of the composite steel-concrete beams.
