چکیده انگلیسی
Carbon Fiber Reinforced Polymer (CFRP) has many superior material properties and can be used as prestressing tendons for prestressing structures instead of steel. A large angle wedge type of anchorage using transverse enhanced CFRP tendons is designed and tested for beam string structure. The results of laboratory tests and numerical analysis under static loading conditions of the prototype of anchorage are discussed. For a wedge with an angle of 10°, the 5-mm-diameter CFRP tendon was anchored successfully, but 7-mm- and 9-mm-diameter were not due to high pressure. The results of test revealed that the sleeve should ensure adequate roughness of internal and external surface, enough wall thickness and cutting width, and appropriate length to avoid some failure mode caused by components themselves. Based on the failure mode analysis of laboratory tests and numerical results, some details were suggested to improve the large angle wedge type of anchorage for applying to large diameter CFRP tendon.
