Application energy theory of strength in the design of reinforced concrete structures on the dynamic impact

Article is devoted to work of monolithic reinforced concrete constructions when subjected to dynamic forces of high-level positions with the energy theory of strength. The purpose of this work is the creation instruments to the internal damping construction and theoretical justification of the proposed design solutions. To analyze the urgency of the given themes originally performed an analysis of the literature of foreign and domestic authors in the form of printed and electronic publications, publications on the Internet, as well as constructive solutions used in the world, to ensure the strength characteristics of structures in congested close to the extreme. Special influenced by the works of Japanese and Chinese scientists in the field of building high-construction. The author of this article carried out experiments showing the dependence of the effect of the type of reinforcement and dispersion of its distribution in the cross section of the element on the strength characteristics of the design. With the help of existing theories explain the processes occurring in the body of reinforced concrete elements, and the distribution of energy in it, depending on the class and the amount of reinforcement in cross-section. The results of analytical calculations to experimental data shown in graphs that demonstrate the effectiveness of decisions. At the end of this article draw appropriate conclusions.
