The Nonlinear Finite Element Analysis to Bonded Post-Tensioned Prestressed Concrete Frame Based on Two-Stage Loading Model

Abstract:

According to the loading character of bonded post-tensioned prestressed concrete frame, the static nonlinear finite programme in this paper could be used to analysis the whole loading process to bonded post-tensioned prestressed concrete frame, which is divided into two different stages . From the stress-strain curve of materials and considering the concrete’ tension harding and compression softening, this programme uses the layered finite element model and arc-length method to analyse the bonded post-tensioned prestressed concrete frame, during the course it considers the material nonlinearity and geometric nonlinearity in the stiffness matrix. Through the contrast to experiment , the result of the programme fits well with the experiment. The programme can be used to compute and analyse the bonded post-tensioned prestressed concrete frame.
