Evolving from the medieval drawbridge, the modern bascule bridge is an engineering marvel.
Category - How Bridges Work
Bridge engineering explained without the textbook.
Of the 617,000 bridges in the United States, only around 3,000 have a movable span. Why so few?
As the old adage goes, use the right tool for the right job. The same goes for retaining walls.
Often marginalized, many bridges just wouldn't exist without them. Retaining walls - the best sidekick a bridge could hope to have.
Externally applied forces on a structure induce internal forces in a structure - and this is how we figure them out.
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.
