... from the literature. Then, a parametric study was carried out on the effect of different variables, such as the elevated temperatures (23, 200, 400, 600 and 800)°C and the center-to-center spacing of the U-shaped CFRP sheets (0 (without), 225, 175, 125, 75 and 50 (full wrapping)) mm. The structural...

... with openings strengthened with different configurations of NSM-CFRP and four slabs that were damaged by heat and repaired with NSM-CFRP. The limitations of the study are the use of only one concrete compressive strength, one specimen, one elevated temperature and opening size used and the application of only...
