Table 7 Prediction of ultimate load for beam specimens
From: Flexural behaviour of recycled reinforced concrete beams strengthened/ repaired with CFRP laminates
Beam No | Specimen description | Cracking Load ECP203-2020 (kN) | Ultimate Load (flexure strength) ECP203-2020 and ECP208-2019 (kN) | Cracking Load (kN) | Ultimate Load (Pexp) (kN) | Ratio Pexp/ Pult | Type of failure |
