Abstract

The paper deals with the assessment of damage in a lightly reinforced concrete beam using the measured values of the first natural frequency. The aim of the presented laboratory experiment was the experimental investigation of the relationship between the degree of cracking and the first natural frequency under defined deterioration conditions. As a result of the test, a definite relationship between the investigated parameters could be demonstrated.
