At the same time, the formation and development of plastic hinges (beam hinges or column hinges) will accelerate, which leads to a more aggravated deformation of the structure under rare earthquake action, resulting in a negative effect to the seismic bearing capacity of the structure. And the interstory drift ratios increase dramatically with the increasing of the corrosion rate. The results show that the seismic performance of the RC frame decreased significantly due to corrosion of the longitudinal rebars. The degradation characteristics of the seismic performance of the corroded structure under severe earthquake were also analyzed. The numerical simulation of the seismic performance of the RC frame structure incorporating different levels of rebar corrosion was conducted using pushover analysis method. SAP2000 software was used to build the finite element model of a six-storey-three-span reinforced concrete (RC) frame structure.
