Abstract
Modern design standards of developed countries have significant differences in the design provisions for determining the bearing capacity of monolithic reinforced concrete slabs for punching and do not fully take into account the features of design solutions and operating conditions. The available design positions are designed for the static loading mode of structures. The stress-strain state of plates for punching under dynamic load is currently little studied, and as a result, there are no methods for determining the bearing capacity of plates for punching under dynamic loading. The article presents the results of experimental and theoretical studies of the bearing capacity of plates under static and dynamic loads. The methodology of experimental studies and the design of prototypes, equipment for conducting power tests are described, the results of studies on the penetration of fragments of the interface of flat reinforced concrete monolithic slabs with a column under dynamic and static loading are presented. A comparison of the destructive load for samples tested under dynamic loading with the destructive load for samples tested under static load is presented. The factors affecting the strength of the plates during punching under dynamic loading are determined. Proposals have been developed to improve the methodology for calculating the strength of flat reinforced concrete slabs when pushing through static and dynamic loads.
