Minimum degree of shear connection rules for UK construction to Eurocode 4 - Available in PDF format only. (P405)

Composite construction has played a major role in the commercial success of the steel construction sector in the UK. However, changes to profiled steel decking over the past decade have had the adverse effect of reducing shear stud resistances in some common situations. Extensive research in this area has led to this new (electronic only) publication. The rules for shear stud resistance and minimum degree of connection, complement those given in Eurocode 4. In so doing they will enable valid designs to be produced for a broader range of beams. FREE TO SCI MEMBERS. AVAILABLE IN PDF FORMAT ONLY
SKU: P405

Developments in decking products and UK construction practice have, in some cases, resulted in shear stud resistances dropping below the values that were traditionally used in design. Lower stud resistances can result in composite beam designs (that were previously possible) becoming impossible, not because insufficient force can be transferred between steel and concrete to generate the necessary moment resistance, but because the maximum number of studs that can be accommodated on a beam is often less than the number of studs needed to satisfy rules for minimum degree of shear connection.

EN 1994-1-1 takes explicit account of three variables that affect minimum degree of shear connection – namely beam span, steel grade, and any asymmetry of the steel section. In this publication a number of other variables are also considered, including the type and orientation of decking, whether or not the steel beam is unpropped during construction, the presence of regular large web openings, and the utilisation in bending of the composite beam. In many cases, consideration of this broader range of variables results in less onerous requirements for the minimum degree, thereby enabling composite solutions that according to the code would be inadmissible.
