Support from above
Rather than support bridges from below, where piers may obstruct a river, it is possible to support bridges from above. The traditional way of doing this is with a suspension bridge. However, modern materials have enabled designers to also build “cable-stayed” bridges. Suspension and cable-staying systems cut down on the number of piers required.
Lesson Objectives
- Students could design and build models of both the above types that demonstrate the differences between them.
- They should be able to explore the loading of suspension and cable stayed bridges. Must understand that the functioning
structural element of a suspension bridge is an inverted arche and that of a cable-stayed bridge is an inverted beam.
