Structural Behaviour of Horizontally Lying Shear Studs

Abstract

In consideration of structural, manufacturing and economic aspects of construction new efficient composite cross sections for buildings and bridges consisting of reinforced concrete slabs and structural steel beams lead to a horizontally lying arrangement of headed shear studs influenced by edge proximity. Compared to common vertical shear studs, the relatively small distance of horizontally lying shear studs from the edge of the slab leads to different bedding conditions of the connectors within the surrounding reinforced concrete material, which results in differing structural and fatigue behaviour of this innovative type of shear connection. In continuation of previous investigations about monotonic longitudinal shear, this paper deals with monotonic vertical shear, monotonic vertical and longitudinal shear, and cyclic longitudinal shear action. On the basis of experimental and theoretical investigations, design rules for future applications are presented.
