Abstract
On an energy basis, the problem of calculating the nonlinear deformation of structures of reinforced concrete multi-storey frames during the destruction of crossbars along an inclined section from special influences caused by structural restructuring of the structural system is solved. Analytical dependences are obtained for determining the parameters of the "moment-curvature" and "transverse force-shear" diagrams in the static-dynamic loading mode of the structures under consideration. The limiting load is determined at which, in the considered structural system of the ring, after applying a special effect in the form of a sudden removal of one of the columns, a special limiting state is achieved with the destruction of crossbars along inclined sections. The obtained design scheme of the destruction of the crossbars of the frame structures under consideration caused by the combined action of bending moments and transverse forces is compared with the destruction scheme obtained experimentally.
