What are the different types of bridges and how do they work?

There are 7 main types of bridges : Arch Bridge, Beam Bridge, Cable-stayed Bridge, Cantilever Bridge, Suspension Bridge, Truss Bridge, Tied Arch Bridge. The way in which the vertical/horizontal stresses are managed dictates the structure of different bridges.

What is a parabolic bridge?

A parabolic arch is an arch in the shape of a parabola. In structures, their curve represents an efficient method of load, and so can be found in bridges and in architecture in a variety of forms.

The most popular bridge in existence is the multiple beam bridge. Most span approximately 40-100 feet and consist of steel or prestressed concrete beams that are supported by abutments or piers.

The deck, the trusses, and the suspenders are the three major components of a truss bridge design. The deck is the main support structure for the weight of the vehicles crossing the bridge.

What is the strongest bridge shape?

Look at a steel or wooden bridge and often you will see triangle shapes making up most of the bridge's support structure. These are called truss bridges. Triangles are structurally the strongest shape because they allow weight to be evenly spread throughout a structure, allowing it to support heavy loads.
