Prediction of Nonlinear Flexural Behavior of Continuous RC Beams Pre-Damaged by Corrosion

Numerical simulation models capable of predicting the nonlinear flexural behavior continuous reinforced concrete (RC) beams with corroded reinforcement were developed. Laboratory tests conducted to validate predictions numerical models. A parametric study was carried out examine effect varying location and severity corrosion on RC beams. The load capacity decreased linearly an increase in corrosion, regardless its location. sagging region was, however, more detrimental than hogging corrosion. rate strength reduction for beam approximately 70% higher that concurrently exhibited poorest performance. both regions 2.7 times only. moment redistribution ratio at ultimate only ranged from 2–22%. highest 22–50% load. simultaneously a constant 18%
