Abstract

The deflection of continuous beam is an important problem in engineering application and theoretical calculation. In this paper, the finite difference method is used to calculate the deflection of the two-span reinforced concrete continuous beam under load. The deflection difference equation of the beam element is used to replace the deflection differential equation of the beam to solve the deflection of the beam. Under the assumption that the continuous beam is continuous at the support, the Abaqus finite element calculation program is used to assist the analysis, and the obtained deflection is compared with the analytical solution of the deflection differential equation of the beam. The research shows that the deflection of the beam calculated by the finite difference method has a small error compared with the real value. The more the number of elements, the smaller the error. The finite difference method preliminarily uses the principle of finite element application to analyze the mechanics of the beam, introduces the corresponding relationship, and carries out the discretization analysis. The calculation process is simple and clear, and has certain advantages compared with the traditional calculation method. The finite element theoretical calculation method is one of the more advanced calculation methods.
