This paper concerns the safety of the simply supported reinforced concrete beams subjected to only bending loads: so that the reliability index and probability of failure are to be calculated. Reliability index was carried out by using Hasofer-Lind method for the doubly reinforced beam with and without retrofitted beams having externally bonded plates (porous and solid) with variable thickness for the limit state in bending. Reliability index can be calculated by using MS-EXCEL. The reliability index for control beam is 0.4022 and the FR-A4 beam is 3.9791. So, the reliability index is high for retrofitted beam only. The Probability of failure (3.5E-05) for FR-C4 beam is very low under the combination of porous plate and 3mm plate thickness.
