- Description
- Reinforced concrete (RC) and steel are materials widely used in the construction sector worldwide because of their cost-efficient durability and structural performance. Nevertheless, repair costs could be very large when infrastructure built using these materials is placed in corrosive environments. Some studies have found that these costs, directly related with damage effects, could increase under given climate change scenarios. Therefore, this chapter focuses on the assessment of costs and benefits of climate adaptation strategies for RC and steel infrastructure subjected to corrosion-induced deterioration and climate change. The adaptation strategies aim to: (i) reduce the impact of corrosion-induced damage increasing the corrosion initiation time for RC structures, or (ii) increase the dimension of steel sheet piles for steel structures to improve the mechanical behaviour in case of corrosion presence. The results of this chapter show that the cost-effectiveness will depend on several factors such as the features of the selected adaptation strategy, environmental exposure, climate change scenario, type of structural component, etc. It could be then concluded that comprehensive probabilistic modelling of deterioration processes combined with reliable climate change predictions and cost-benefit analysis are paramount to formulate 'no regrets' or 'win-win' adaptation schemes.
