Editing Cable-stayed bridge (section)

===Self-anchored suspension bridge===

A [[self-anchored suspension bridge]] has some similarity in principle to the cable-stayed type in that tension forces that prevent the deck from dropping are converted into compression forces vertically in the tower and horizontally along the deck structure. It is also related to the [[suspension bridge]] in having arcuate main cables with suspender cables, although the self-anchored type lacks the heavy cable anchorages of the ordinary suspension bridge. Unlike either a cable-stayed bridge or a suspension bridge, the self-anchored suspension bridge must be supported by [[falsework]] during construction and so it is more expensive to construct.
