Strengthening of constructions
Original language description
Fiber-reinforced polymer (FRP) composite materials have developed into economically and structurally viable construction materials for buildings and bridges over the last 20 years. Nowadays, there are commonly used for strengthening of constructions (strips, bars, fabrics) and also for making structure elements. Strengthening of the members or structures are made by sticking FRP materials to the structure or by its prestressing. One of the progressive methods to strengthening RC structures (buildings, bridges) is to use external FRP reinforcement. Main problem of strengthening by external FRP reinforcement is bond presstresing force to usually cracked concrete. In the past, it has been done experimental tests of bond area of FRP strips, but without strengthening this area by FRP fabrics. The goal of the experiment is exactly to define transfer of internal force thorough anchor zone FRP strips where the anchor zone is strengthened with the help of FRP wraps.
