ABSTRACT
Composite steel-concrete structures with the steel substructure as a truss can offer a number of benefits from the point of view of material consumption, both in the case of civil or industrial buildings and in the case of road and railway bridges. For composite truss structures the design methodology is not presented in detail in the Eurocode 4. The design implies some particularities that are not included in the literature. In this paper an adaptation of Euro norms EN 1994-1-1:2004. Eurocode 4 - Design of composite and concrete structures – Part 1-1: General rules for buildings and EN 1994- 2:2004. Eurocode 4 - Design of composite and concrete structures – Part 2: General rules and rules for bridges to the design of bridge superstructures with steel trusses are presented. A railway bridge superstructure with a 30.0 m span was calculated after the presented methodology and a number of observations and comments useful in the design activity were formulated.

Keywords: composite steel-concrete decks, steel trusses, bridge design
