FEM Analysis of Bi-Prestressed Concrete Beam

Abstract:

Based on ANSYS software, the solid modeling method was performed to build the half model of bi-prestressed concrete beam. And the solution for solve the problem such as the constitutive equation, failure criteria , the method of modeling,the infliction method of prestressed was summarized in this paper. The heating-cooling method was used to achieve the bi-prestressed.The simulate method was reasonable while the built mode was performed to simulate the pre-arch and bearing capacity, simulate the pre-arch and bearing capacity of pre-pressed bi-prestressed concrete beam by FEM software ,and compared with the experiment results. And summarized the handling of the constitutive equation,failure criteria,the infliction method of prestressed, the method of modeling ,and so on. All of the method will provide reference for the research of Bi-prestressed concrete beam.
