What is an arch bridge?

Arch bridges use one or more arches as the main structural component, with the arches positioned beneath the deck. This method dates back many thousands of years, with stone and brick being the most commonly used materials. However, in modern times you will see arch bridges constructed from concrete.

What is the principle of arch bridges?

Whatever material is used the principle remains the same: An arch bridge uses compression – downward pressure from the deck travels laterally towards the keystone and to the supporting structures at each end of the bridge ( the abutments).

How does a cable stay bridge work?

Water ran in a trough at the top level of the bridge. Cable-stayed bridges have straight cables extending from towers to hold up the roadway deck. As those cables (stays) pull up on the deck, they also pull toward the mast, and thus the roadway deck structure must be strong enough to resist a large compressive force.

What are the straight members of a truss?

The straight members that make up a truss are struts or “sticks” of steel in modern bridges. The struts form triangles, which are inherently rigid. Truss bridges carry weight effi¬ciently because each of their straight members is either pulled (in tension) or pushed (in compression).
