duration of the impulse action on the reinforced concrete beam depends on a number of factors. Thus, within a specified range of these factors the greatest interval of impulse duration is obtained under variation of the striker velocity within the interval from 0.1ms to 2.9ms. Assuming that the impulse duration defines one of the main wave frequencies of vibrations one may conclude that frequencies will vary in the range from 300Hz to 10000Hz. The algorithm developed in this study allows us to find a constructively acceptable combination of factors (mass, radius and velocity of the striker, elasticity modulus and thickness of the gasket), which will provide the required spectrum of wave frequencies for vibration diagnostics of the elements of reinforced concrete structures.
