Abstract
Composite steel-concrete structural systems exhibit inherent architectural and structural advantages over other alternatives. In particular, their high strength-to-weight ratio and the improved stiffness make composite steel-concrete structures ideal for high rise buildings. The flexural strength of composite beams is greatly influenced by the strength and durability of the shear connectors between the structural steel beam and the concrete slab. In this context, this paper deals with the numerical prediction of the ultimate capacity of headed stud shear connectors, AJAX One Sided Blind Bolts and Lindapter Hollow Bolts. The proposed continuum finite element models are developed in the general purpose package ABAQUS. Eight-node solid elements are used to model the various connection components such as concrete slab, structural steel beam, one sided blind bolts, hollow bolts and headed stud shear connectors. Special attention is given to the modelling of the geometric and mechanical characteristics of the bolts included the shank, head and nut. Initially, the actual force-slip relationship is adopted from available experimental data to compare with the finite element model.
