CONCEPTS/RESEARCH

· CABLE-STAYED BRIDGE

A cable-stayed bridge is a bridge that consists of one or more columns (normally referred to as towers or pylons), with cables supporting the bridge deck.

· TRUSS BRIDGE

A truss bridge is a bridge composed of connected elements (typically straight) which may be stressed from tension, compression, or sometimes both in response to dynamic loads.

· SUSPENSION BRIDGE

A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. This type of bridge dates from the early 19th century, while bridges without vertical suspenders have a long history in many mountainous parts of the world.
