Mechanical Behavior Experiment Of Anchorage For FRP-tendons

Fiber Reinforced Polymer(FRP) is applied to all kinds of complicated environment With its light weight, high strength, excellent durability and gradually takes the place of steel. But FRP reinforcement material is anisotropic materials, and its transverse compressive strength is far less than the longitudinal tensile strength, so FRP cannot be directly like steel clamping tensile test on the test machine. This paper puts forward two kinds of new type bonding anchorages base on ACI code, research on performance test for anchorage and tensile properties of FRP reinforcement,and the main research contents:1.Studies the working mechanism of the new type bonding anchorages.Using of the two kinds of new type bond anchorage can reduce the length of the specimen,and test the tensile strength of FRP reinforcement material effectively.2.Using the large-scale finite element analysis software ABAQUS to carry out the influnce by clamp plate anchorage, analyses the anchor length, anchor cup angle,friction coefficient, and clamping piece material to the performance of clamp wedge anchor,so as to optimize the various parameters, and give a reasonable parameter combination to anchorage for tensile test and prestressed anchorage.
