[en] A composite structural member is a member made of at least two parts with different materials, interconnected by a shear connection which allows to design the member as a single structural member. Composite members combining steel and concrete are the most common solutions met in practice and is the topic of the present paper. As reflected in the above definition, the shear connection plays a key role in the global behaviour of composite members, as the latter should limit the slip between the concrete part and the steel part but also to ensure the transfer of shear forces between the two materials to allow the composite member to act as a monolith structural element. The present paper summarises the general concept behind the design strategies for shear connection in steel-concrete composite beams, the code requirements and recent research out-comes allowing to extend the code requirements to new structural composite solutions such as shallow floors.
