Bridging the Gap

October 2007
Weekly Reader News - Senior;10/19/2007, Vol. 86 Issue 7, p6
The article presents information on the four different types of bridges found in the U.S. The beam bridge has its weight supported by piers. The arch bridge uses abutments for support. The truss bridge is described as a bridge made up of triangles which allows even distribution of weight and can span long distances. The suspension bridge is described as a system of towers attached to cables from which the road hangs and truss systems and anchorage that provide stability.

    Information on different types of bridges is presented. The beam bridge is the most basic kind. A log across a stream is a simple style of beam bridge. Highway bridges are often beam bridges. You can easily recognize an arch bridge, because it has arches holding it up from the bottom. The truss...

    The article discusses physical factors affecting the functions of bridges. All structures seek balance through at least two gravitational factors, tension and compression. Material is in tension if it is being pulled and material is in compression if it is being pushed. In suspension bridges,...

    A suspension bridge is more appropriate type of structure for extremely long-span bridges due to the rational use of structural materials. Increased deformability, which is conditioned by the appearance of the elastic and kinematic displacements, is the major disadvantage of suspension bridges....
