Reinforced concrete is one of the basic building materials. Therefore, it is essential to study the behavior of reinforced concrete structures in subcritical and critical states. In this paper, we discuss the performance of a test stand designed to study deformation processes in the elements of full-size models of reinforced concrete structures subjected to quasi-static and dynamic loadings. The design of the stand and its main technical characteristics have been developed based on the results of numerical simulations of the evolution of deformation processes in the tested structure in going from elastic to inelastic state, which finally leads to its destruction. These simulations allowed us to design the foundation and load frame of the stand, to define the parameters of loading devices able to provide a wide range of deformations, to choose apparatus for recording the successive stages of damage accumulation and macroscopic fracture occurrence.
