What Are The Characteristics Of A Suspension Bridge

Dec 20, 2021

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.

Compared with other bridge structures, suspension bridges can use less material to span longer distances. Suspension bridges can be built relatively high to allow ships to pass underneath. There is no need to build temporary piers in the center of the bridge during bridge construction. Therefore, suspension bridges can be built on relatively deep or relatively rapid currents.

 

What other features does it have?

(1) Suspension bridge is more flexible, so it is suitable for the needs of strong wind and earthquake area. The more stable bridge must be stronger and heavier in these areas. To

(2) The sturdiness of the suspension bridge is not strong, and traffic must be temporarily interrupted under strong wind conditions

(3) Suspension bridge is not suitable for heavy railway bridge

(4) The tower of the suspension bridge exerts a very large force on the ground, so if the ground itself is relatively soft, the foundation of the tower must be very large and quite expensive.

(5) The suspension cables of the suspension bridge are not easy to replace after they are corroded.
