| Abstract | ||||
| Corrosion or other types of degradation caused by aging, etc. under environmental influences, poor routine maintenance leads to deterioration of concrete structures, which required repairing of these structures. In addition, structures, which needs to increase load carrying capacity because of changing usage, or considering some of design and construction defects due to poor quality control, must strengthened. So studying the effect of different methods of strengthening is very important. Using of fiber-reinforced polymers (FRP) is one of the more widely accepted methods for strengthening and repairing of reinforced concrete (RC) and prestressed concrete structural elements. FRP had a number of benefit characteristic such as lightweight due to low density, easy handling, high strength, high stiffness and high corrosion resistance, which make it durability and require less maintenance. | ||||
