Experimental Studies of Reinforced Concrete Beams, Taking into Account the Reaction of Thrust on Compliant Supports Under Short-Term Dynamic Loading

When designing reinforced concrete beam structures with limited horizontal displacement on supports under short-term dynamic loading, it is necessary to take into account the occurrence of a thrust reaction. The presence of a thrust leads to a significant increase in strength and crack resistance of structures, and when yielding supports are used, to the increase in their energy intensity. The purpose of the experimental study is to study the feasibility of using yielding supports in dynamically loaded spacer structures. The paper presents the results of experimental studies of reinforced concrete beam structures with a thrust on yielding supports under short-term dynamic loading. The influence of yielding supports on the strength, deformability and crack resistance of reinforced concrete structures with thrust was considered. The results of experimental studies indicate a positive effect of the use of yielding supports in dynamically loaded structures with a thrust.
