[en] The rules in EN1994-1-1 concerning the resistance of shear connections
in composite beams with headed shear studs and steel sheeting relies on push-out
tests, which have been performed between the late seventies and the early nineties
of the last century. In the recent years, new geometries of metal decking have
appeared on the market with the target to reduce the volume and weight of the
concrete slab and to maximise the slab efficiency.
The influence of these new geometries on the load bearing behaviour of shear
connections has to be verified. Amongst others, the RFCS research project
DISCCO investigated the shear stud resistance in combination with such novel
steel decking. It turned out that, the current EN 1994-1-1 rules need to be modified
especially for metal decking with narrow and deep deck ribs. Alternative analytical
equations for the estimation of the shear resistance have been derived and
statistically evaluated according to EN 1990. Details are presented in this
contribution.
