Seismic Fragility Analysis of RC Shear Wall with Age-Related Degradation for Different Failure Criteria

Reinforced concrete (RC) shear wall has been used various structures because it has excellent resistant capacity under seismic load. Especially shear wall system has been used at the containment and auxiliary building of nuclear power plants (NPPs) due to safety and shielding effectiveness. The degradation of concrete is often caused by aggregate expansion and chemical damage. Degradation leads to reduction of strength and ductility. Various failure criteria must be therefore considered for seismic fragility analysis of degraded shear walls. In this study, we deal with seismic safety of RC shear wall with age-related degradation considering different failure criteria
