The box girder bridge was a popular choice during the roadbuilding expansion of the 1960s and many new bridge projects were in progress simultaneously. Most of the bridges still under construction at this time were delayed for investigation of the basic design principle. LRFD SIMON – NSBA’s complimentary software for preliminary steel plate and box girder design. Simon has a long history of serving as a key tool in helping bridge engineers efficiently design and analyze steel bridges and should be used to realize efficiencies and demonstrate the practicality of a steel bridge for a specific application. Analysis and design of prestressed concrete box girder bridge. Ever since the development of prestressed concrete by Freyssinet in the early 1930s, the material has found extensive application in the construction of long-span bridges, gradually replacing steel which needs costly maintenance due to the inherent disadvantage of corrosion under aggressive environment conditions.
A computer program has been developed which will automatically design or analyze simple or multispan composite or non-composite steel box girder bridges for highway systems.
