A suspension bridge is a form of bridge in which the deck is suspended on vertical suspenders from below suspension cables. The first examples of this kind of bridge were constructed in the modern era. In many hilly areas of the world, simple suspension bridges with no vertical suspenders have a long history.
There are several varieties of suspension bridges in addition to the one this article described, which is the most popular variety. In the type discussed here, cables are suspended between towers, and vertical suspender cables transfer the live and dead loads of the deck below, which is where traffic passes. With this setup, the deck can be level or arched upward for more clearance.
Since any force placed on the bridge is converted into tension in these major cables, the suspension cables need to be fixed at both ends. Beyond the pillars, the major cables extend to deck-level supports and connections with anchors in the ground. Hangers, which are vertical suspender cables or rods, support the road. In other cases, the bridge will typically have two smaller spans, running between either pair of pillars and the highway, which may be supported by suspender cables or their own trusswork. In some cases, the towers may sit on a bluff or canyon edge where the road may proceed directly to the main span. In the latter scenario, the outboard will have very little arc.
The Global Suspension bridge market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
When it opens to traffic, China’s Lvzhijiang Bridge will be the first single tower, single-span suspension bridge in history. The bridge, which spans a Lvzhijiang (also known as the “Green Juice River ”), would facilitate and speed up transport in the rural and picturesque Yunnan region. The bridge, which is supported at both ends by cables and is built in a mountain valley with a V form, looks as though it defies gravity and is recognised as an engineering marvel. It is only held up by one tower on one side.
