Abstract: The advantages of so called double-head studs over conventional stirrups in concrete, namely the employment of the full yield strength immediately behind the anchorage, more efficient confinement near the surface and ease of placement are the main reasons for the increasing number of their applications ([2], [3] & [5]). Their development has been mainly driven through experimental investigations. This paper will outline the approach that will be followed in a numerical study that is currently in progress at the University of Calgary.
The research is mainly focused on the local anchoring effects and the confinement provided by the double-head studs. A three dimensional finite element analysis is chosen as a suitable means to model the studs and the surrounding concrete. Classical plasticity theory will be used to take into account the different material properties of concrete and steel in a phenomenological sense. A common remedy to mesh sensitive results in finite element analysis occurring from the use of softening material formulations will be shortly addressed.
