Diagnostic analysis of dams means here assessment of possible structural damages (due to, e.g., alkali-silica reaction in concrete). Such damages may be primarily self-equilibrated stresses due to material expansion, elastic stiffness degradation, decrease of compressive and tensile strength, and of fracture energy. The procedure presented in this paper is intended to perform such diagnosis deep inside the concrete dam and is based on “ad hoc” devised substantially novel mechanical experiments, on their finite element modelling and on deterministic parameter identification through the minimization of the discrepancy norm between measured quantities and their counterparts computed as functions of the sought parameters.

Abstract

Diagnostic analysis of dams means here assessment of possible structural damages (due to, e.g., alkali-silica reaction in concrete). Such damages may be primarily self-equilibrated stresses due to material expansion, elastic stiffness degradation, decrease of compressive and tensile strength, and of fracture energy. The procedure presented in this paper is intended to perform such diagnosis deep inside the concrete dam and is based on “ad hoc” devised substantially novel mechanical experiments, on their finite element modelling and on deterministic parameter identification through the minimization of the discrepancy norm between measured quantities and their counterparts computed as functions of the sought parameters.
