By　using　nonlinear　FEM　program　ABAQUS,　the　mechanical　behaviors　of　circular　concrete　column　specimens　confined　with　FRP　under　axial　compression　were　analyzed,　considering　the　nonlinear　behavior　of　concrete　under　triaxial　state　and　the　passive　confinement　of　FRP　for　concrete.　The　interaction　between　concrete　and　FRP　was　studied,　and　the　influence　of　FRP　layers　on　the　ultimate　strength　and　strain　of　concrete　was　studied.　The　results　indicate　that　the　numerical　results　agree　well　with　the　test　results.　Nonlinear　FEM　analysis　can　better　predict　the　axes　compressive　properties　of　FRP　confined　concrete　column.　The　ultimate　strength　and　strain　of　FRP　confined　concrete　increase　with　the　increase　of　FRP　layers.　The　confinement　effect　of　FRP　on　concrete　has　obviously　improved.　The　confinement　force　of　FRP　on　concrete　will　exert　mainly　after　concrete　yield.　Based　on　the　experimental　results　and　FEM　analysis,　the　relationship　between　the　ultimate　strength　and　strain　of　FRP　confined　concrete　and　FRP　confinement　eigenvalue　is　derived.
