Strength of reinforced concrete structures under extreme mechanical impacts

Abstract

The article deals with the issues of substantiation of the strength of reinforced concrete structures under extreme mechanical impacts. The focus is on the interaction of the outer containment and the heavy aircraft. Modern physical models and methods of direct numerical modeling of processes are used with taking into account nonlinear behavior of materials. These approaches are verified on original model problems. The impact of a heavy transport aircraft on an undeformed reinforced concrete wall is determined. The thickness оf the outer containment of the reactor building varies. The strength of structures with taking into account the pliability of soil bases on which reinforced concrete structures are located is also studied.
