Trusses have not been described here as a type of bridge, because a truss is more a type of construction than a type of bridge. Arches, beams and cantilevers have all been built in truss construction. A truss is one of the means of saving weight by placing material where it can be most effective, using the principle of triangulation to achieve rigidity. Other solutions are I-beams, tubes and box-girders. Please click here for the main pages about trusses. Where do we find trusses? Click here for examples. This page includes two computer programs which calculate the forces in very light trusses carrying very heavy loads. The examples assume a load of one unit: the forces can be scaled up or down for other loads. Click here for more pictures. Click here to download a program simulating a kingpost truss.
