The technique of using CFRP for strengthening R.C members in a structure was started in 1980s and became one of the most interesting researches in all over the world. It is proper to know the main reason for strengthening R.C members was to increase it's withstand unexpected and extra loads, i.e. changes in usage of a structure. Researches has indicated that carbon fiber reinforced polymer (CFRP) can be used in all kind if structure components such as column, beams, slabs and walls. CFRP are applied to enhance shear strengthening, flexural strengthening and improving ductility of compression members. Researches has indicated that R.C beams strengthened using CFRP in tension face have performed greater flexural strength than primary flexural strength. On the other word, a proper repair improves the function and performance of structures, restore and increase its stiffness and strength, increase the appearance of the concrete surface, provide water hardness, preventing ingress of the aggressive species to the steel surface durability. As mentioned earlier need of strengthening structures is due to aging deterioration, increase in loads, corrosion of steel reinforcement and advancement in the design codes and knowledge. Little research has been carried out shows that previous design didn't have adequate knowledge on the behavior of structure. High overestimated the capacity of concrete and the permissible concrete stress was taken in the early 1960s to be 1.1 fou which is currently 0.95fcu in SI units. These particular deficient beams will fail in a no ductile manner once reaching their limit. As a result to what happen, pre 1970s designs may be low in strength abiding to the current codes. 2024-07-31T08:25:40Z 2024-07-31T08:25:40Z 2012 Resource Types::text::Final Year Project https://irepository.uniten.edu.my/handle/123456789/33147 en_US application/pdf
