Flexural Performance of Concrete Beam Strengthened with Multi-supports Unbounded Prestressed CFRP Plate

摘要

The multi-supports unbonded prestressed CFRP plate reinforcement technology is introduced and ABAQUS finite element software is used to establish a multi-supports unbounded prestressed CFRP plate reinforced concrete beam model. The bending stiffness, bearing capacity and deformation regulation of finite element model is analyzed and compared by changing the number and spacing of the support and degree of prestressing. And the effect of changing these parameters on bearing capacity of concrete beams strengthened with multi-supports unbonded prestressed CFRP plate is also analyzed and compared.
