3-D Finite Element Simulation for Prestressed Box Girder Bridges

Pan Xue-zheng

Abstract

Finite element analysis method for prestressed concrete bridge is introduced.The prestressed bridge finite element analysis module is redeveloped based on ANSYS software.It is able to bring material and geometric nonlinear effects into the analysis,for analyzing mechanical performance and local stress characterization of this kind of structure.For an example,model for an actual project with prestressed concrete box girder is built,combined with Solid45 for simulating concrete,and Link8 for simulating prestressed tendon.
