… The mechanics of prolonged displacements of a hinged-restrained reinforced concrete
beam under the influence of longitudinal vibrational force with eccentricity were examined.
Over time, due to prolonged dynamic force and concrete creep, stress redistribution occurs
between concrete and reinforcement, leading to beam displacements. The problem of creep
was resolved using the theory of aging. Two methods were employed: the Bubnov-Galerkin
method with a small parameter and Runge-Kutta; Bubnov-Galerkin method with initial …
