However, continuous truss bridges do not experience the tipping forces that a cantilever bridge must resist because the main span of a continuous truss bridge is supported at both ends. The result of collapse of a continuous truss bridge (the Francis Scott Key Bridge). It is possible to convert a series of simple truss spans into a continuous ...
