FIELD: construction industry. SUBSTANCE: process can be applied for selective or complete nondestructive test of finished construction reinforced concrete articles. Process includes several stages. First inspected article is put on supports in accordance with operating conditions and vibrations of varying frequency required by form, specified operational parameters and multiplicity of repetition of these vibrations are excited. Then dependence of values of dynamic parameters of article on value of rate of change of frequency of vibrations for specified level of excitation energy is determined. Values of change of dynamic parameters of inspected article depending on value of rate of change of frequency of vibrations are compared with corresponding changes of values of dynamic parameters of standard article obtained under same inspection conditions. EFFECT: increased accuracy of measurements taken in process of nondestructive inspection with simultaneous rise of its informativity. 2 cl, 5 dwg
