Modern anchorage systems are increasingly being used by design engineers as load transfer mechanisms. Choosing the right anchor system requires a review of current technical references, performance criteria and reliability information from prequalification tests. Fortunately, design engineers can avail of information from the American Concrete Institute and the Comite Euro-International du Beton which publish data on the performance of anchor system.

Epoxy-coated anchors used for stabilization of the dam at the Occoquan River, Virginia, exhibited more creep movement and seating losses than bare-wire strands due to a difference in the material's behavior. Epoxy-coated anchors have provided double corrosion protection to the dam. Studies conducted by Harza Engineering Co. show that the Post-Tensioning Institute criteria may be unsuitable for epoxy-coated filled strand since it is based on the bare-wire strand. Lift-off tests are the best method for a long-term evaluation of anchor performance.
