Abstract:

Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically varying profile provides superior performance compared to a conventional linear conic anchor. It was also found that an anchor with a bond release agent on the surface between the socket and the resin plug results in a lower peak shear stress compared to a bonded anchor. The combination of a parabolic anchor and a bond release agent permits use of a wider range of resins as socketing agents is less sensitive to construction tolerances. Mechanical anchors were much more variable in their ability to hold load and were seldom capable of developing the full tensile capacity of the tendons.
