ABSTRACT:
In a composite beam, a connecting element interconnects a concrete slab and a downwardly depending structural steel member. The connecting element is L-shaped having an elongated base member which is secured by one or more fastening elements to the structural steel member and an elongated anchor strap extending angularly from the base member and incorporated into the concrete slab. Supporting webs are secured to and extend between the base member and the anchor strap. The part of the base member encircling the openings through which the fastening elements pass is deformed to provide rounded recesses. The anchor strap can be made more rigid by forming a corrugation-like recess extending in the elongated direction of the strap. When a force is applied to the anchor strap causing it to move angularly away from the base member, the support webs cause the adjacent surfaces of the base member to act as deformation zones relieving the force on the connection between the base member and the structural steel member.
