The results of experimental and theoretical studies to determine the viscosity modulus of concrete under static-dynamic loading are presented. The considered model of concrete deformation is based on the plasticity theory of concrete and reinforced concrete of G.A. Geniev, whose deformation dependences are constructed taking into account the adopted static-dynamic loading regime. According to a specially developed and patented technique, the results of uniaxial tests of concrete prisms were obtained in a two-stage regime of their static-dynamic loading and the parameters of concrete deformation in time were experimentally determined, which allow experimentally to obtain the viscosity modulus of concrete of different classes. It is shown that the viscosity modulus of concrete and its dynamic strength depends not only on the class of concrete but also on the level of its static loading at the first stage. The results obtained are of interest for solving problems, the strength, and deformability of sections of reinforced concrete structures at a special limiting state, to ensure the protection of buildings and structures from progressive collapse.
