Abstract: High-capacity saw-tooth connections 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 which has 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.
Based on the investigations carried out in the Institute for Structural Design II, University of Stuttgart, with Prof. J. Schlaich, the paper presents the most important results of the research on the behaviour and design of saw-tooth connections. The paper describes the flow of forces in the connection area and explains the interdependent factors which govern the dimensioning of the connection. Emphasis is laid on the new geometry of the teeth, which is derived from a close look into the stress distribution in front of a single tooth using non-linear analyses. Reference is made to Prof. J. Schlaich’s paper [1] also submitted for this Symposium and a more extensive joint paper [2].
