Final report on Contract No. 7210-SA/129, 130, 131, 325, 524; 1 July 1996 to 30 June 1999

This research project was undertaken to resolve a series of technical problems related to the application of high-strength steel S460 in structural design. The problem of plate buckling phenomena of high-strength steel plate girders was investigated experimentally and by numerical studies. The influence of the reinforcement, the concrete strength, load eccentricities, the placement of shear studs and geometrical variations were investigated, and led to recommendations for new design rules. Work on the problem of lateral torsion buckling of composite beams without any connections between the concrete slab and the high-strength steel girder showed that for each type of steel girder, the buckling can be prevented by a present concrete slab. Other studies showed that the design rules for composite beams made of normal-strength steel and normal as well as high-strength concrete have to be improved. Finally, bolted connections were tested and the results have been used to improve and extend the design aids for joints of S460-members.

The results of the research can be transferred into new design rules for high-strength steel by implementing them in ENV 1993 (Design of Steel Structures) and ENV 1994 (Design of Steel and Concrete Composite Structures). s).
