Abstract
A fiber reinforced polymer (FRP) anchor configured for field testing includes a precured end portion at a first end of the FRP anchor, a plurality of rovings extending from the precured end portion to free ends at a second end of the FRP anchor wherein the rovings being splayed in a first plane, and a pair of plates disposed at opposite sides of the rovings relative to the first plane. The plates are cured to the splayed rovings.
Claims17
A fiber reinforced polymer (FRP) test anchor configured for field testing, the FRP test anchor comprising:
- an FRP anchor comprising a plurality of rovings extending from a first end of the FRP test anchor to an opposite second end of the FRP test anchor;
- a pair of metal plates at the second end of the FRP test anchor;
- FRP rovings wrapped around the metal plates;
- wherein the first end of the FRP test anchor comprises a cured end portion of the plurality of rovings of the FRP anchor;
- wherein the plurality of rovings are splayed in a plane as the plurality of rovings extend from the cured end portion toward the second end of the FRP test anchor;
- wherein the metal plates are disposed at opposite sides of the plane of the splayed rovings;
- wherein the metal plates are cured to the splayed rovings;
- wherein the FRP rovings are wrapped entirely around the metal plates and the splayed rovings that are clamped between the metal plates;
- wherein the metal plates are configured to couple the FRP test anchor with a field test system;
- and
- wherein the metal plates are configured to permit the field test system to measure tensile strength of the FRP anchor.
