Refers to a bridge with cables (or steel chains) suspended and anchored on both sides (or at both ends of the bridge) through pylons as the main load-bearing members of the superstructure.
The cable geometry is determined by the equilibrium conditions of the forces and is generally close to a parabola. A number of suspender rods are lowered from the cable to hang the bridge deck. Stiffened beams are often set between the deck and the suspender to form a combination system with the cable to reduce the deflection deformation caused by the load. It is composed of suspension cable, tower, anchorage, derrick and deck system.
