Abstract
Rigidity of a suspension bridge is attributed to the dead load as well as the rigidity of stiffening girder (or truss). This paper deals with the theory and the structural elements of the unstiffened suspension bridge with heavy deck, the rigidity of which is given intensionally by dead load only. As examples, the test results in two of this type of bridge are discussed. It is noteworthy that this type of a suspension bridge is sometimes economical and preferable according to circumstances.
