Assessment of Long-Term Performance of a 50-Year-Old Jetty in the South of Iran

A detailed investigation was carried out on a 50-year-old reinforced concrete jetty in a commercial port of Iran to assess the long-term performance as well as the structural condition. Destructive and nondestructive tests such as carbonation depth, electrical resistivity, chloride diffusion, X-ray diffraction, compressive strength, and water absorption were performed. The results revealed that the good quality of the concrete has protected reinforcement from corrosion. However, structural analysis showed minor weakness in some elements of the jetty; thus, consulting engineers finally decided to strengthen some elements with fiber-reinforced polymers.
