| Summary: | The purpose of this case study is to review the effect and contribution of CFRP laminates on shear strengthening and repair of reinforced concrete beams. To date, the method is yet to become a mainstream application due to number of economical and design related issues. The current experimental work consists of one control beam and four beams wrapped with CFRP laminates [5]. The CFRP configuration are either fully wrapped or U shaped with orientation at 0°/90° and 45°/135°. This case study then identifies several theoretical model developed by Triantafillou [6]; Triantafillou and Antonopolous [7]; Khalifa and Nanni [8][9]; Adhikary et al. [10]; Carolin and Täljsten [11], and Täljsten [12] along with three design codes i.e. ACI 440 [2], BCS [3] and fib [4] towards predicing the shear contribution of CFRP laminate. The results for both experimental and theoretical value were then compared in term of mean percentage difference to select the best theoretical shear prediction value. |
