The analytical prediction of residual flexural strength corroded beams has been revisited in the context relatively larger size reinforced with diameter tension bars to exclude size-effect proposed modelling and improve further accuracy method. Most past research, including that conducted by authors, used smaller beam specimens generate test data for modelling. A new experimental programme was undertaken using 48 width 200 mm depth varying from 215 315 mm, 16 18 diameter. were subjected a degree corrosion damage accelerated then they tested four-point bending determine their flexure capacity. When two-step procedure, authors an earlier work beams, applied this work, it found theoretical predictions consistently lower than actual beams. search more compliant method accomplished proposing correction factor replaces previous one correctly taking into account bars. In order show method, published other researchers have compared values predicted comparisons clearly yields which are good agreement experiments, lending confidence serve as reliable tool predict capacity concrete beam.
