When designing reinforced concrete structures subjected to intense dynamic loading, it is necessary to take into account the simultaneous influence of the thrust reaction, which leads to significant increase in strength and crack resistance, and the influence of yielding supports used to increase the energy intensity of structures. The purpose of this study is to assess feasibility of yielding supports application in thrust structures. The paper presents results of experimental studies of reinforced concrete beams with thrust on yielding supports under short-term dynamic loading. The paper considers the influence of thrust on strength, deformability and crack resistance of reinforced concrete structures under short-term dynamic loading, as well as the joint application of yielding supports and limitation of horizontal displacement of the support contour. The results of the study indicate positive effect of yielding supports application in structures with thrust.
