Different Types of Bridges

The load-bearing structure, whether convex, flat, or concave, determines the basic principles of bridge design

Fremont, CA: Bridges are an important part of civil engineering and a frequent aspect of the built environment. The load-bearing structure, whether flat, convex, or concave, determines the basic principles of bridge design. Below mentioned are different types of Bridge designs.

• Beam bridges

Steel truss or prestressed concrete units get used to producing beam bridges, either simple beam or cantilever constructions. The horizontally self-supporting simple beam bridge transmits stresses upwards through piers or abutments. The piers in the center of the beam transmit loads to the cantilever bridge.

• Tied Arch Bridges 

The linked arch bridge is intriguing, with a metal arch structure supported by vertical ties between the arch and the deck. However, a bottom chord connects the points of the arch construction. It works similarly to a bowstring does. The vertical ties convert the downward pressure from the arch structure to the bridge deck into tension.

• Arch bridges

Arch bridges are load-bearing arch in compression, and their strength and stability allow them to handle more weight than beam bridges. In addition, the bridge's horizontal deck can be supported from above or below by the arch.
