Structural assessment of the coupled influence of corrosion damage and seismic force on the cyclic behaviour of RC columns

Steel bar corrosion, which is considered to be a significant degradation issue in reinforced concrete (RC) structures, may cause premature failure during seismic events. Many experimental studies have been conducted investigate the coupled effect of steel corrosion and force on structural behaviour RC columns. However, modelling response corroded columns has received comparatively less attention. An accurate assessment corrosion-damaged extend life span reduce maintenance costs. In this study, we applied finite element method developed numerical model simulate performance The was account for corrosion-induced cracking bond deterioration between depending spatial variation corrosion. (FE) validated using results obtained from three different sets tests available literature with an average ratio ranging initial severe levels. proposed demonstrated excellent correlation all results, thereby making it suitable investigating terms stiffness, strength, displacement capacity, pattern. After validation, used localised uneven distribution cyclic
