摘要：
U-wraps. Three-dimensional finite-element models for the material properties of a carbon-fiber-reinforced polymer and concrete were constructed and validated using experimental data for two RC beam specimens. Their failure mechanism is represented as shifting from the shear-tension in the control beam to the shear-compression in the strengthened beam. Parametric studies were performed to determine the effect of the number of CFRP layers and CFRP U-wraps on the overall shear performance and failure mechanism of the RC beams.
