Parameter analysis of a cable-stayed bridge without backstays [PDF]

A cable-stayed bridge without backstays is an important branch of the cable-stayed bridge family. It tilts the bridge tower to one side and removes the backstay cable, relying on its own weight to balance the tension in the slanted cables.
