Abstract
Fiber Reinforced Polymer (FRP) systems have gained much popularity as a method for reinforcing existing concrete structures. However a variety of sudden failure methods, such as debonding, delamination, and creep rupture have led to the development of code limitations on the strength that an FRP system can be considered to provide. The uncertainty brought on by the failure methods mentioned above has become the topic of much research. Researchers have proposed fracture and strength based methods to predict debonding. However, there are many environmental and durability issues that have not been considered in these prediction. These uncertainties make FRP strengthened concrete beams a good candidate for a health monitoring system. In this a paper a detailed look at current methods of predicting debonding is presented. Additionally, effects that the environment and durability have on debonding are presented. Finally, monitoring systems for FRP strengthened concrete beams are discussed. Two monitoring schemes are proposed.
