Abstract
The problem of concrete properties identification and damage location in model beam type constructions is considered on the basis of application of experimental vibration analysis. As a simple analysis model, beam structures are considered defect-free and with defects. Based on the experimental approach, the model vibrations under shock and vibration excitation are analyzed. On the basis of analytical modeling, the dynamic modulus of elasticity, the velocity of sound in the beam, and the location of the defect are calculated. A technique and an example of the location of a defect in beam type constructions are presented.
