The decision to perform an extraordinary maintenance or a seismic retrofit of existing RC buildings should be based on rational criteria, which lead into account a number of factors that are able to define the cost-effectiveness of the investment. Among them the age of the concrete structure and its normal depreciation are key. The paper proposes value-time functions for the two main depreciation factors: age, and income decay. Empirical formulas have been developed to estimate the economic life of concrete structure on the basis of analysis of these depreciation functions.
