Abstract
The aim of this paper is to inform about the fabrication and erection of the bridge load-bearing steel structure, SO205-00. The bridge is located on the 2,097th km over the Majersky creek (Majerský potok). The load-bearing structure of the bridge deck is composed of a composite steel-concrete grate structure acting as a continuous beam over spans of 33 m + 3 x 40 m + 33 m. The steel part of the load-bearing structure is made of welded built-up beams with a constant height of web 1440mm and, according to the static design requirements, various thickness and width of flanges. The connection of the steel-concrete bridge deck with the steel structure is ensured by means of shear connectors welded to the upper flange. In the paper are listed new standards (STN EN) and rules (TKP20, MVDRR) valid at production and erection time of the objective bridge load-bearing structure.
