Numerical investigation of corroded reinforced concrete exterior beam‐column joints under quasi‐static reverse cyclic loading
The performance of corroded exterior beam‐column joints (BCJs) at varying levels of corrosion‐induced damage has been investigated in the current research study using numerical simulation. Two reinforcement detailing regimes, that is, non‐seismic traditional detailing in accordance with IS 456:2000 and seismically detailed as per IS 13920:2016, were adopted. A three‐dimensional (3D) nonlinear finite‐element (FE) model has been proposed using the ABAQUS software. The accuracy of the numerical model was verified by the results reported in the experimental study available in the published literature. The numerical results reported a significant reduction of approximately 54.24% and 43.9% in the peak load‐carrying capacity of maximum corroded non‐seismically and seismically detailed BCJs, respectively, when compared with that of uncorroded specimens. The corrosion level influences the damage progression. The present FE model was observed to correctly capture the ultimate failure mode of the tested specimens, indicating a good correlation with the experimental results.
