Abstract
This paper presents an experimental study on shear strength, stiffness and ductility of
demountable shear connectors in metal decking composite slabs through push-off tests.
Twelve full-scale push-off tests were carried out using different concrete strength, number of
connectors and different connector diameter. The experimental results showed that the
demountable shear connectors in metal decking composite slabs have similar shear capacity
and behaviour as welded shear studs and fulfilled the minimum ductility requirement of 6mm
required by Eurocode 4. The shear capacity was compared against the prediction methods
used for the welded shear connections given in Eurocode 4, AISC 360-10, ACI 318-08 and
method used for bolted connection in Eurocode 3. It was found that the AISC 360-10 method
overestimated the shear capacity while the ACI 318-08 method underestimated the shear
capacity of specimens with single shear connector per trough. The Eurocodes method was
found to provide a safe prediction for specimens with single and pair demountable connectors
per trough. In addition, prediction methods given in both AISC 360-10 and ACI 318-08 for
welded shear studs overestimated the shear capacity of specimens with 22 mm diameter
demountable connectors that failed in concrete crushing.
