Spatiotemporal Distribution of Deformation Processes in Reinforced Concrete Structure under Shock-Wave Exposure (Simulation & Experiment)

Abstract

The article deals with the experimental and theoretical study of deformation processes in a reinforced concrete structure, which is a part of a hybrid precast/cast-in-place building on a scale of 1:2. The propagation of elastic waves caused by shock impact on various structure parts is analyzed. The results of numerical simulation of elastic wave propagation through structural elements are presented. Based on the data of mathematical modeling, experimental algorithms for structure investigation have been developed. The parameters of the shock impact and the characteristics of the equipment measuring the deformation response have been selected. The data of a physical experiment on shock-wave exposure on a structure in the elastic deformation mode are presented.
