Generalised fracture mechanics approach to the interfacial failure analysis of a bonded steel-concrete joint

Wouter De Corte, Peter Helincks, Veerle Boel, Jan Klusak, Stanislav Seitl, Geert De Schutter

Steel-concrete joints are often made by welded shear studs. However, this connection reduces the fatigue strength, especially in situations where locally concentrated loads occur with a large number of load cycles e.g. in bridge decks. In…
