What Is A Suspension Bridge

Suspension bridge, also known as suspension bridge, refers to a bridge in which cables (or steel chains) suspended by pylons and anchored to both banks (or both ends of the bridge) are used as the main load-bearing members of the superstructure. The cable geometry is determined by the force balance condition, which is generally close to a parabola. Many suspension rods are hung from the cables to hang the bridge deck. A stiffening beam is often set between the bridge deck and the suspension rods to form a combined system with the cables to reduce the deflection and deformation caused by the load.
