Abstract

Results of modeling and experimental studies on determination of parameters of reliability and durability of reinforced concrete structures are presented. Studies were carried out in relation to beam-type structures. Experiments were carried out using vibrodynamic test methods. The calculation and processing of the results of vibration diagnostics were carried out using the software complex of finite-element analysis ANSYS, as well as using the methods of mathematical statistics and correlation analysis. As a result, the relationship between the parameters of the natural oscillation frequencies of the material and its strength (concrete class) is established. The obtained dependencies can be used in the development of methods for assessing the bearing capacity of structures of various objects of the energy complex.
