Abstract
There is a need to retrofit existing concrete structures. There are many different ways to increase the performance of a concrete structure, FRP (Fiber Reinforced Polymer) strengthening being one. This method is commonly used across the world to improve the load carrying capacity of concrete structures. In this paper, an overview of a Swedish guideline for the FRP strengthening of concrete structures is presented. The guideline covers designing for bending and shear as well as for confinement, and there is also a discussion of the need to proper workmanship and the choice of the right material for strengthening.
