Abstrait:

The impact of climate change on ambient temperature and relative humidity along with the present CO2 levels are speeding the corrosion process of reinforced concrete structures. The alarming cost of the associated reduction of the service life of structures, which is estimated to cost 3% to 4% of the Gross Domestic Product (GDP) of industrialized countries, has put the spotlight on the importance of introducing the issue of climate change on the new generation of Eurocodes. Amongst the strategies to tackle the problem, design-phase measures seem not to be always cost- effective, nevertheless, measures during service-life are generally the most expensive. This paper discusses the potential strategies to be addressed by structural codes to tackle the problem of climate change-induced corrosion, considering aspects such as the cost-benefit analysis, viability, and the large uncertainty involved in climate change evolution.
