As it is widely known, the effect of seismic actions on the existing structures, which are located on coastal areas, maintains a pending issue, given the harsh degradation of reinforced concrete, due to corrosion factor. Although corrosion phenomenon of steel reinforcement is time dependent; nevertheless, this type of issues is not mentioned in the existing technical standards. Consequently, the demanded terms and conditions to predict the remaining mechanical performance, with the use of degradation laws concerning the remaining strength and ductility of the steel rebars, are not available yet to the engineers who are responsible for the rehabilitation (before and after seismic phenomena). |
