This paper discusses the advantages of using pultruded continuousfiber reinforced polymer laminates for post-strengthening structures. Criteria for evaluating and designing with these materials are suggested. In Europe, retrofitting by externally bonding carbon fibre reinforced plastic (CFRP) laminates has been shown to be less expensive than the technique of external steel plate bonding, especially if ease of handling is a dominant cost factor. The ease of handling the light weight CFRP laminates helps to reduce labour costs.
