As　a　new　structural　material,　FRP　(fiber　reinforced　plastics)　features　light　weight,　high　strength,　corrosion　resistance,　etc.,　and　have　a　bright　future　when　used　for　a　new　type　of　prestressing　tendon　in　engineering　structures.　The　horizontal　shear　strength　of　FRP　tendon　is　relatively　low,　which　will　affect　the　shear　strength　of　concrete　beams　pre-stressed　with　FRP　tendons.　This　paper　carried　out　nonlinear　analysis　of　the　shear　behavior　of　concrete　beams　pre-stressed　with　FRP　tendons　based　on　ANSYS　software,　the　effect　of　various　parameters　on　shear　behavior　were　detailed　discussed.　The　results　of　finite　element　analysis　showed　that　nonlinear　analysis　were　in　good　accordance　with　the　experimental　results,　which　can　well　simulate　the　shear　behavior　of　pre-stressed　concrete　beams　with　FRP　tendons.　©　2011　IEEE.
