Abstract

This paper evaluates the effect of climate change on the corrosion, aging and push over curves of pile-supported wharves. With rising sea levels, temperatures, and relative humidity, significant effects on the resistance and ductility of these materials have been observed. This research considered three scenarios for pitting corrosion in prestressed cables, both with and without climate change considerations. The results indicate that climate change leads to a significant increase in the corrosion rate of materials, ultimately resulting in a reduction in the structural capacity.

Specifically, findings reveal that after 50 years, the corrosion rate due to climate change has increased by 94%. This could have serious implications for the design and maintenance of pile-supported wharves, highlighting the need for special attention in future planning. Therefore, the effects of climate change must be seriously considered in the design and evaluation of marine structures to ensure their safety and proper performance.
