Self-anchored Suspension Bridge




A self-anchored suspension bridge is a Suspension Bridge in which the main cables do not attach to the ground via large anchorages; instead, the main cables attach to the ends of the road deck, which experiences compression equal to the tension in the cables. The result of this design is that the bridge does not exert any horizontal pulling forces on the ground; the bridge foundations need only support the bridge's weight. Therefore, the self-anchored suspension bridge design is well-suited for construction atop elevated piers, or in areas of unstable soils where anchorages would be difficult to construct.
