Bridges BY JOHN KYLE. Bridge’s?  What is a Bridge do you Know?  The Question is What do you think a bridge is ? Well a bridge is something that lets.

Abutment: supports at the end of a bridge that carry the load and keep the ends from spreading out.

Structures What things do I need to find out in order to predict if what I design will stand up to the use I intend to put it through?

Bridge Designs Bridges are often built over huge landmasses or bodies of water. Their design depends on their function and location. We will take you through.

Bridges

Types of Bridges Girder or Beam Truss Arch Suspension Cable-Stayed

Girder or Beam Bridges Simplest type of bridge Consist of a beam supported on both sides by piers Shortest span

Truss Bridge Sometimes considered a type of beam bridge Span greater distances Consist of many beams placed in stable triangular shapes Distribute load more evenly over greater distances

Arch Bridge Curved shape Old design Stable but with a limited span Load is distributed evenly over both sides

Suspension Bridge & Cable-Stayed Bridge Have longest spans Use cables to suspend load Rope bridge to Golden Gate bridge Cable-Stayed Bridge Use cables in load distribution. Cables run diagonally from the towers to the girder.
