Abstract

In this paper, a finite element software ABAQUS is carried out to calculate the ultimate load bearing capacity of the concrete under the restraint of prestressed bar. According to the failure criterion of Mohr-Coulomb, the calculation method of ultimate bearing capacity is put forward, and get the ultimate bearing capacity of concrete constrained by prestress in the beam through calculating. The analysis shows that the stress state of the concrete can be changed by prestress and the ultimate bearing capacity of the beam is improved. By comparing the calculation results, it is concluded that the theoretical formula of the failure criterion of Mohr-Coulomb is similar to the actual results, which can accurately calculate the ultimate bearing capacity of beam end.
