Finite Element Modeling Method and Analysis of Self-Compacting Concrete Prestressed T-Beam

Abstract

Self-compacting concrete could be poured under the action of gravity, without vibration, and has good working performance. It could reduce the noise during production, and reduce the labor of workers. In recent years, more and more scholars begin to study the concrete. In this paper, ABAQUS finite element software is used to simulate the self-compacted concrete prestressed T-beam under different parameters, using the self-compacting concrete constitutive model. The cooling method is used to simulate the prestress applying, and the performance of beam is analyzed. It is found that the bearing capacity of the member improves with the increasing of the reinforcement ratio, the prestress increases the stiffness of the member, and reduces the deflection of the member, but the ductility is reducing with the increasing of prestress.
