Time to complete: 40 hours. In French, a rudimentary simple suspension bridge is known by one of three names, depending on its form: pont himalayen ("Himalayan bridge": a single footrope and handrails on both sides, usually without a deck); pont de singe ("monkey bridge: a footrope with overhead rope); and tyrolienne ("Tyrolean": a zip-line). The deck of the suspension bridge is the load-bearing element of the structure. Simple suspension bridges are restricted in their use to foot traffic. The deck experiences both forces. These loads are transferred both to the towers, which carry them by vertical compression to the ground, and to the anchorages, which must resist the inward and sometimes vertical pull of the cables. Notable simple suspension bridges include: under rope design bridges made on short distance, A simple suspension footbridge in Finland. The experiment simple suspension bridge allows the experimental investigation of the tension in the main cable of a suspension bridge under different load conditions. February 25, 2019 was a very bad day for our 80′ suspension bridge that we built in 2005.

In such bridges, the deck of the bridge follows the downward and upward arc of the load-bearing cables, with additional light ropes at a higher level used to form a handrail. Light bridges with decking, and sufficient tension that crossing the bridge does not approach climbing, may be used also by pack horses (and other animals), equestrians, and bicycle riders. More commonly, the footrope is accompanied by one or two handrail ropes, connected at intervals by vertical side ropes. Here, simple suspension bridges are made by training the roots of the Ficus elastica species of banyan tree across watercourses. The very lightest bridges of this type consist of a single footrope and nothing more. Found inside – Page 550In the past, simple suspension bridges were constructed in mountainous areas, as pedestrian and animal crossings. There is a reference [4] to the Tsimovo ... These include a stressed ribbon bridge, which is closely related to a simple suspension bridge but has a stiffened deck suitable for vehicle traffic. On a simple suspension bridge, the main cables (or chains) follow a hyperbolic curve, the catenary. Simple suspension bridges using iron chains are also documented in Tibet and China. Stand them up on end, facing each other, several inches apart. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. A very light bridge, constructed with cables under high tension, may approach a suspended deck bridge in the nearly horizontal grade of its deck. Simple suspension bridges, for use by pedestrians and livestock, are still constructed, based on the ancient Inca rope bridge but using wire rope and sometimes steel or aluminium grid decking, rather than wood. Handrails are necessary because these bridges are prone to oscillate side to side and end to end. The bridge was originally built in 1889 by George Grant Mackay . [1][2] Although simple suspension bridges and "simple" suspended deck bridges are similar in many respects, they differ in their physics. One type of bridge that withstands earthquakes well is a suspension bridge, or a bridge supported by a cable system. Suspension bridges have benefited our everyday lives since John A. Roebling perfected the suspension bridge design in 1845 and built the Allegheny Suspension .
