carrying capacity when using four NJF ropes was estimated as 17.2%, which agrees with those of 18.6% (obtained from the analytical investigation) and 14.3% (obtained from the finite element analysis). 4. Post-tensioning of reinforced concrete beams with high-strength steel strands achieves the highest load-carrying capacity. Still, it is prone to corrosion when basalt fibre-reinforced polymer (BFRP) bars are used in place of steel reinforcement, resulting in significant deflection, which may not satisfy the serviceability criteria. Hence, using NJF ropes for post-tensioning beams with steel reinforcement, protected by concrete, is a good combination for structural applications. 5. Strengthening structures using natural jute fibre (NJF) ropes is promising, especially when considering the advantages of this green material and its positive impact on the sustainability of structures.
