Abstract
The article presents the results of theoretical studies of reinforced concrete beams, taking into account the limitation of horizontal displacement on supports under short-term dynamic loading. In studies, the deformation of the structure is considered in the conditionally elastic and plastic stages. It has been established that the presence of thrust leads to a significant increase in strength and a decrease in the deformability of structures, both in the conditionally elastic and plastic stages. The paper reflects the results of a numerical calculation of reinforced concrete beam structures with thrust under short-term dynamic loading based on the obtained analytical dependencies. The effect of the thrust reaction, namely the rigidity of the support contour, on the dynamic coefficient of reinforced concrete structures is considered in comparison with structures without expansion. The results of numerical studies indicate a positive effect of the expansion reaction in dynamically loaded structures at all stages of their dynamic deformation.
