Behaviour and design of steel and composite beam connections to composite walls

Abstract

This paper presents a combined experimental and numerical study on the static and cyclic behaviour of composite wall-to-steel/composite beam connections. In the experimental phase, seven composite wall-to-steel beam connections fabricated from both S250 mild steels and S690 high-strength steels were tested under static and cyclic loads. Owing to the adoption of various design solutions, tested composite wall-to-steel beam connections exhibited significant different failure modes. However, all of such steel beam connections exhibited satisfactory rotational capacities. Meanwhile, six composite wall-to-composite beam connections were fabricated from S250 mild steel and tested under both static..
