Numerical Simulation on the Form of Reinforcement of Reinforced Concrete Beam with Openings

Abstract:

In order to research the stress performance of reinforced concrete beam with different forms of reinforcement around the openings, a numerical simulation on reinforced concrete beam with circle openings is made by using the finite element software. The constitutive relation of concrete offered by the 2010 edition of code for design of concrete structures and the concrete damaged plasticity model is adopted in this article. The damage factor is introduced in the process of modeling, which can reflect the damage of beams with different forms of reinforcement directly and help to reveal the failure mechanism of members. Thus we can propose the optimization of reinforcement method.
