The Measuring Test and Finite Element Analysis for Prestressed Concrete Beams
Based on one prestressed frame beam in an actual project, both the indirect measuring test and the finite element numerical simulation about the reinforcement prestress are made. The test and simulation results show that the effect prestress obtained from indirect measure methods can reflect the prestress history relatively well. Meanwhile, the indirect measure method has the advantages of low cost and easy operation, which can be exploited and developed in general projects so as to get the stress history of the prestressed reinforcement in time and reduce potential security threat.
