Studu of spatial problems of dynamic stability of reinforced concrete frames

Abstract

The article proposes a method for constructing areas of dunamic instability of reinforced concrete frames in the space of parameters (freguency and amplitu de) of seismic and operational dynamic impacts that cause the apperance of longitudinal forces in the bars of structures. which periodicallychange in time and lead to an unlimited inerease in amplitudes of transverse vibrations when the values of these parameters are in the areas of instabilitu.
