خلاصه مقاله:
Strengthening of structures to avoid future damages is inevitable in different conditions. In recent years, fiber reinforced polymer (FRP) sheets are vastly used for strengthening of different concrete members. In this paper, to evaluate the effect of FRP plates on damaged or non-damaged members, an extensive experimental and numerical program is prepared. For this purpose, 10 beam specimens are built. Some of the beams are made under loading condition and their load - deformation curves are prepared; then, the damaged beams are strengthened with CFRP and GFRP using epoxy resin and have been tested under loading. The second part of the beam specimens are strengthened before loading and then their load- deformation curves are prepared. Some specimens are analyzed using Finite Element Method [1]. The results of numerical model and experimental research work show the improvement of bearing capacity of strengthened damaged beams compared to the non-damaged ones.
