High-capacity saw-tooth connections, as against those with headed studs, enable the highly concentrated transmission of large forces between steel members and slender concrete slabs. The connection is made from a welded or cast steel bar provided with a saw-tooth shaped geometry along the interacting face of the connection. The geometry of the teeth is universally applicable for most sorts of connections and ensures a very high fatigue strength of the connection. In this paper the initial typical engineering approach to this development and its early practical applications are described as well as its later application based on an improved geometry of the teeth. With respect to its detailed scientific investigation resulting in this improved new geometry, reference is made to the work of Volker Schmid and his paper also submitted for this Symposium and a more extensive joint paper.
