Abstract
Abstract At design supporting structures for coatings of transport buildings and structures for northern areas in accordance with regulatory requirements, their resistance to progressive (chain) collapse is determined. To ensure safety, the structural system of the building in the northern areas must ensure its durability and stability, at least for the time necessary to evacuate people. To improve the reliability of the supporting structures of coatings proposed, developed and researched the system of redundancy of the type-sprengel. The scenario of collapse and an algorithm for calculating the intact elements of the coating system are proposed. The results of the study are given, which indicate that by varying the rigid parameters of the backup system it is possible to achieve minimal damage from the collapse of individual elements of the system.
