| Abstract: | The method of nonlinear analysis of prestressed concrete beam with FRP tendons in FEM software ANSYS was introduced.In the paper,some problems,include the choice of elements,constitutive equations,the infliction of prestressing force and the process of modelling and solving,were discussed.Then the finite element analysis of a unbonded prestressed concrete beam with FRP tendons was made in ANSYS and the load-distortion curve was attained.Comparing with the test data,it indicated that the method was applicable. |
