ABSTRACT

This paper concentrated on the improvement of shear bond strength through the insertion of shear connectors between the composite deck slab and the supporting steel beam. A total of 24 specimens were cast using M40 grade concrete and grouped into two categories (with and without composite action between a deck slab and the supporting steel beam). In every group, two steel sheet profiles were introduced in depths of (55mm and 75mm). For each profile, six specimens were experimentally studied with different shear spans. In each three specimens, one specimen was subjected to static load while the rest were exposed to cyclic load as per Eurocode 4. The experimental findings indicated that the presence of shear connectors has significantly increased the shear bond characteristics.
