Abstract:
In this paper bond tests conducted on short NSM-bar anchorages arepresented and results are evaluated to determine the effect of design variables ondevelopment capacity. Specimens were designed so as to minimize spurious secondarystresses along the bonded length. Parameters of the study were the groove dimensionsand the embedment length. Bars were CFRP reinforcement with sandblasted surfacecharacteristics. Analytical expressions are derived from first principles so as to interpretthe observed experimental trends. The parameters of the analytical bond stress - slipmodel are calibrated to the experimentally derived bond-slip relationships in order toestablish a limit-state model for post-installed reinforcement, for practical upgradingapplications.
