In this paper, a group of demountable shear connectors have been developed and tested to assess their potential and suitability in terms of replacing welded shear studs. The experiments showed that these demountable shear connectors can be easily demounted after testing and have similar capacity and behavior to those of welded shear connectors. After the numerical simulation method had been validated against experimental observation, a parametric study was carried out to understand the effect of concrete grades and stud collar sizes on the shear resistance of demountable shear connections. Simple design calculation methods for welded shear connections or anchoring connections provided in European and American standards were checked to the suitability for assessment of this headed demountable shear connector.
