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.

Abstract
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.File in questo prodotto:
