Estimating plastic strain and residual strain capacity of earthquake-damaged steel reinforcing bars
Modern seismic codes are based on capacity design and the hierarchy of strength philosophy that allows inelastic response in case
of severe earthquakes. Thus, in most traditional systems, earthquake damage develops at well-defined locations in reinforced concrete (RC)
structures. Plastic hinges form in beams, in coupling beams, and at the base of columns and walls. There is a perceived strong demand from
government and industry to develop techniques for assessing damage to steel reinforcement bars embedded in cracked structural concrete
