The primary function of a bridge deck is to support the vehicular vertical loads and distribute these loads to the steel superstructure. This chapter provides practical information regarding the decking options and design considerations for steel bridges, presenting deck types such as concrete deck slabs,
During the past years, traffic load models adopted in codes of practice for designing bridge structures have noticeably evolved. In modern codes, static models adopted previously, representing physically existing heavy
Calculate the internal forces and moments according to Eurocode’s principles. By modelling the bridge deck (geometry and stiffness to represent its actual behaviour in the best way) And by applying the load cases. Section and member analysis. Stress limitations at ULS and SLS.
This chapter provides a general description of the various concrete deck types, a discussion of the basic structural behavior of concrete decks, and an overview of major design and detailing considerations. Finally, a design example for a reinforced concrete bridge deck is provided.
