Truss bridges tension and compression

Web705 Words3 Pages. A truss bridge is one that is composed of triangular patterns formed from either metal or wooden beams. Each individual member of the truss component of the bridge is subject to compression and tension from either ends of the actual structure. The top beam will always receive the most compression while the bottom beam receives ...
