FEM Analysis Of The Reinforced Concrete Beam With Bonding Steel Plate

The reinforced concrete structure with bonding steel plate is a method which is widely used in the method of reinforcing concrete. Concrete reinforcing technical specification uses the ultimate strength theory, which indicates that the stress on Q235is familiar with the stress on HRB335, the reinforced concrete structure with bonding steel plate and the ordinary concrete structure have the same desdruction process, the steel comes to the yield stress limitation at first, and then the concrete crush.Based on the characteristics of the reinforced concrete beam with bonding steel plate、the theory of FEM analysis and the ANSYS software, I make the finite element model at first,then I put forward to the relationship between the stress and the strain in every component of the concrete beam. I use SOLID65for concrete, LINK8for rebar, SOLID45for the glue and Q235.Through the establishment of the ANSYS finite model in this paper, I have an analysis on the reinforced concrete beam with bonding steel plate and the ordinary concrete beam. Through the analysis, I draw my conclusion.
