At the beginning of the design process, there may be many questions posed. But by the end, all such questions should have an answer.
Analysis is the determination of the demands on a structure.
How do you want your bridges to be judged? As engineering marvels or as just plain ugly?
Preliminary bridge design is more of an art than a science and getting off to the right start is key to a successful project.
Bridge bearings - the glue - or the grease - between the superstructure and the substructure.
The concept of pre-stressing is one which every structural engineer wishes they had discovered.
