Repairing of continuous one-way reinforced concrete slabs by CFRP composites
This paper presents an experimental investigation of the performance of two-span reinforced concrete slabs repaired by CFRP composites against flexural loads. Thirteen continuous reinforced concrete (RC) one-way-slabs were cast, with dimensions of 2400 mm length, 500 mm width, and 100 mm thick. The...

| description | This paper presents an experimental investigation of the performance of two-span reinforced concrete slabs repaired by CFRP composites against flexural loads. Thirteen continuous reinforced concrete (RC) one-way-slabs were cast, with dimensions of 2400 mm length, 500 mm width, and 100 mm thick. The first specimen had no strengthening at all and was considered a reference slab (Control). The rest of the slabs were repaired using different configurations of external bonding CFRP sheets and NSM bars. Before the repairing process, the slabs were subjected to 40% and 65% of the control slab ultimate load. The test was done under two-line loads. Moreover, the effect of different lengths, spacing, repairing techniques, and damage ratios were studied in this work. The finding shows that the repairing methods were effective in improving the ultimate load capacity ranges between 42% to 70% and reducing the deflection by about 11% to 25%.
