The enhanced structural performance of Reinforced Concrete (RC) columns retrofitted by Fiber Reinforced Polymer (FRP) composite jackets, has been well demonstrated and an increasingly large number of bridge and building columns have been retrofitted with such jackets in the United States and elsewhere. However, seismic damage such as debonding between the jacket and the column that can consider...

Tension stiffening behavior of post-cracking concrete is an important phenomenon which has been extensively studied for reinforced concrete structures. Although externally bonded fibre reinforced polymer (FRP) composites are widely used for strengthening existing RC structures, it remains unclear to what extent the tension stiffening of post-cracking concrete is quantitatively influenced by the...

Repairing deteriorated concrete bridge piers using externally wrapped FRP (fiber reinforced polymer) composites has been proven as an effective approach. This technique has also been applied to low-rise building structures. Failures in FRP-wrapped concrete structures may occur by flexural failures of critical sections or by debonding of FRP plate from the concrete substrate. Debonding in the FR...
