The Influenced of Localized Corrosion on the Natural Frequency in the Reinforced Concrete Beam

This study presents the use of natural frequency for the identification of damage location in detecting the location and severity of corrosion in reinforced concrete beam models. The simply supported beam was modeled with five different corrosion factors, f using DIANA Release 9.1 software. The simu...

The simply supported beam was modeled with five different corrosion factors, f using DIANA Release 9.1 software.
