Steel – Concrete Composite Bridges : Sustainable Design Guide

Steel-concrete composite bridges, both road and rail, have experienced a veritable boom in France since the late  1970s.  Whilst  highly  competitive,  primarily  in  the  area  of  medium  span  structures,  composite  bridges  have  consistently  extended  their  range  of  usage  through  development  specifically  towards  large  spans,  the  design of which has progressed ever further away from prestressed box girder and steel structures. This  guide  reviews  in  detail  the  design  and  construction  of  the  most  common  composite  road  structures,  namely  girder  and  box  girder  bridges.  It  is  intended  not  only  for  Clients  and  Owners,  but  also  design,  construction and methods engineers. The  present  guide  therefore  replaces  and  supersedes  the  Sétra  guide  entitled  "Ponts  mixtes  acier-béton  bipoutres / Guide de conception" [twin girder steel-concrete composite bridges / design guide], published in October  1985,  updating  of  which  was  necessary  in  relation  to  specific  points  (new  design  and  material  standards,  wide  structures)  as  well  as  complementing  of  major  areas,  such  as  box  girder  deck  design  and  construction  methods.  This  new  guide  also  replaces  and  supersedes  Sétra  technical  report  No.  8,  entitled  "Montage des ponts métalliques" [steel bridge construction], published in 1973.
