Fig. 13 Design solutions of new single-span structure: a steel–concrete span structure; b steel
girder span structure with orthotropic deck
main girders located at a distance of 11.9 m from each other is recommended for
use. It is proposed to rebuild damaged piers using steel lattice structures made of
extensional units.
Probable variants of terrorist attacks on the Darnytsky Rail-Road Bridge crossing
over the Dnieper River are considered, the methods for eliminating their consequences are developed and the most likely scheme for destruction of bridge crossing
structures is established. Within the framework of these methods, two design solutions are proposed for replacing damaged section of the superstructure. It is recommended to use a steel girder superstructure with an orthotropic deck, which differs
not only by high manufacturability and process-ability for installation, but also by
accelerated terms of work with minimal labor costs.
