Abstract [en]

Strengthening of existing structures with Carbon Fibre Reinforced Polymers (CFRP) is a method that has been more common in the building sector during the last decades. The materials strength in relation to its weight is a huge advantage but the lack of knowledge in the building sector results that professionals uses more proven materials such as steel to strength structures. In this report five minor projects in which steel was the strengthening material has been analysed to see if CFRP could be a competitive strengthening material considering mainly practical and economical aspects. The main purpose of this report was to evaluate when CFRP is the most suitable option for strengthening of concrete structures. The results showed that CFRP was applicable in every project but the total cost were higher comparing to the steel solution in four out of five projects. The results indicate that it is difficult to motivate CFRP regarding the economical aspect in relation to minor project that were evaluated in this report. Nevertheless, the tendency is that the advantages with CFRP is more useful when there are more comprehensive projects such as advanced steel works and when it is necessary to save room volumes.
