NEW TEST DATA ON THE STRENGTH OF GROUTED CONNECTIONS WITH CLOSELY SPACED WELD BEADS

A series of laboratory tests were undertaken to investigate the effect of closely spaced weld beads on the axial static strength of grouted pile sleeve connections. This paper describes the experimental techniques used and the results of the investigations are presented along with recommendations to designers for implementation of the results. Grouted connections are used extensively throughout the offshore industry in the piling details for fixed structures and in some repair techniques. These results provide some justification for a reassessment of the limits on allowable weld bead spacing imposed by the API and UK Department of Energy, particularly API in which the limits may be non-conservative. The results indicate that the relationship between bond strength parameter and the weld bead height to spacing ratio (h/s), remains linear up to h/s values of around 0.075. At values beyond 0.0075 the linear relationship is no longer valid and the presence of further weld beads leads to a reduction in the bond strength parameter.
