| 摘要： | This study examined the effectiveness of fiber-reinforced plastic on reinforced concrete and steel structures. Three types of carbon fiber-reinforced plastics (FRP) materials, Replark, I9, and Flat Carbon Vinyl (FCV) Ester plates, were tested to record the changes in the behavior of concrete beams with the application of the plates. FRP performance was monitored under controlled laboratory conditions. A field study was the conducted on two bridges in Ohio. Strains and deflections in the concrete structures under a static load were measured both before and after the installation of the fiber-reinforced plastic plates. Results showed that FRP aided in decreasing strains on concrete and steel, it also reduced beam deflections. All FRP-reinforced beams showed aspects of failure, however, from steel yielding to local shear failure. Strain and deflection values were too small to form conclusions regarding the FRP performance on the two bridges. |
