Nonlinear Numerical Simulation on Shearing Performance of RC Beams Strengthened with Steel Wire Mesh-Polymer Mortar

摘要

The numerical analysis by using software ANSYS for shearing performance of rectangular reinforced concrete beams strengthened with steel wire meshpolymer mortar formed U-shaped are studied. The numerical results are compared with experimental results. Two models, named separated model and composite model respectively in software ANSYS, are used to analyze the beams. In separated model, strains of longitudinal steel bars and stirrups are in good agreement with the test results. In composite model, strains of longitudinal steel bars are also in good agreement with the test results, while strains of stirrups are not. But both of steel wire deformations obtained by two models of software ANSYs are slightly different with the tests results. Cracks distribution in beams obtained by software ANSYS, comparing with test results, are not very obvious.
