Investigation of the Influence of Cracks on Vibration Processes in a Reinforced Concrete Structure

Abstract:

The validity of the mathematical model describing the propagation of vibrations in a reinforced concrete (RC) structure was verified by comparing the experimental and numerical data. The proposed model allowed one to perform numerical experiments aimed at comparing vibrorecords obtained from the structure without defects and the structure with cracks. A numerical experiment was performed aimed to explore the changes in vibrorecords when cracks appear in the structure. Based on the results these experiments, an informative diagnostic parameter controlling crack nucleation and propagation in the reinforced concrete structure was derived.
