Rotation capacity of composite joints for slim-floor beams. (LAJ19.D)

The analysis of a composite beam-to-column structure requires
knowledge about, on the one hand, the behaviour of beams and
columns and, on the other, the joints between such elements.
For beam-to-column joints, for example, the lack of appropriate
design rules forces structural engineers to model joints as
pinned, despite the fact that a certain joint rigidity and bending
resistance is available because of the upper reinforced concrete
slab.
In this context, a research program with experimental and
numerical investigations was initiated at the University of
Luxembourg [1]. This aim of this research was to identify the influence
of two major joint components – the reinforced concrete
slab and the steelwork connection – on the behaviour of
composite joints under a hogging bending moment. Eight experimental
tests were performed on...
