Floating Suspension Bridge
A floating suspension bridge is a type of suspension bridge supported by towers built on floating pontoons which are tethered to the seabed. The design is intended to overcome the difficulties of building suspension towers in locations where the water is particularly deep. no such bridges have been built, but a project is underway to build one in Norway, at Bjørnafjord, designed by engineer Ian Firth.

Suspension Bridge
A suspension bridge is a type of bridge in which the deck (bridge), deck is hung below suspension wire rope, cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges, which lack vertical suspenders, have a long history in many mountainous parts of the world. Besides the bridge type most commonly called suspension bridges, covered in this article, there are other types of suspension bridges. The type covered here has cables suspended between towers, with vertical ''suspender cables'' that transfer the Structural load#Live load, imposed loads, transient load, live and Structural load#Dead load, dead loads of the deck below, upon which traffic crosses. This arrangement allows the deck to be level or to arc upward for additional clearance. Like other suspension bridge types, this type often is constructed without the use of falsework. The suspension cables must be anchored at each end of the bridge, s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underspanned Suspension Bridge
An underspanned suspension bridge (also upper deck suspension bridge pages 517-520) is a rare type of suspension bridge that was developed in the early 19th century. Overview It differs from its ancestor, the simple suspension bridge, in that the deck is raised on posts above the main cables. The raised deck is less stable than a deck laid on or hung below the cables, and very few underspanned suspension bridges have been built. Examples include Guillaume Henri Dufour's Pont des Bergues (1834);Peters, Tom F., ''“Transitions in Engineering: Guillaume Henri Dufour and the Early 19th century Cable Suspension Bridges”'', Birkhauser, 1987, and James Smith’s Micklewood Bridge. pages 95–96 Similar bridges were proposed by Robert Stevenson in 1820 for a bridge over the River Almond between Edinburgh and Queensferry, and by a Mr. Armstrong for a bridge at Clifton. Part of the roadway on the land side of the piers of the Hammersmith Bridge was constructed in this manner. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable-stayed Bridge
A cable-stayed bridge has one or more ''towers'' (or ''pylons''), from which cables support the bridge deck. A distinctive feature are the cables or stays, which run directly from the tower to the deck, normally forming a fan-like pattern or a series of parallel lines. This is in contrast to the modern suspension bridge, where the cables supporting the deck are suspended vertically from the main cable, anchored at both ends of the bridge and running between the towers. The cable-stayed bridge is optimal for spans longer than cantilever bridges and shorter than suspension bridges. This is the range within which cantilever bridges would rapidly grow heavier, and suspension bridge cabling would be more costly. Cable-stayed bridges were being designed and constructed by the late 16th century, and the form found wide use in the late 19th century. Early examples, including the Brooklyn Bridge, often combined features from both the cable-stayed and suspension designs. Cable-stayed ...

Float (nautical)
Floats (also called pontoons) are airtight hollow structures, similar to pressure vessels, designed to provide buoyancy in water. Their principal applications are in watercraft hulls, aircraft floats, floating pier, pontoon rhinos, pontoon causeways, and marine engineering applications such as salvage. During World War II the United States Navy Civil Engineer Corps developed a modular steel box (pontoon) for the Seabees to use. It was an industrial sized Lego system of pre-drilled pre-cut angle iron and steel plate that could be assembled anywhere for which they became famous. They used them to facilitate amphibious landings. With the pontoons Seabees assembled docks, causeways, and rhinos to whatever size needed. They allowed landings on Sicily where no one thought possible. They ferried Patton across the Rhine and put the Marines ashore on Okinawa. They would be used during the Korean War in the landing at Inchon in 1950 and again in Lebanon during the 1958 Leban ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norway
Norway, officially the Kingdom of Norway, is a Nordic country in Northern Europe, the mainland territory of which comprises the western and northernmost portion of the Scandinavian Peninsula. The remote Arctic island of Jan Mayen and the archipelago of Svalbard also form part of Norway. Bouvet Island, located in the Subantarctic, is a dependency of Norway; it also lays claims to the Antarctic territories of Peter I Island and Queen Maud Land. The capital and largest city in Norway is Oslo. Norway has a total area of and had a population of 5,425,270 in January 2022. The country shares a long eastern border with Sweden at a length of . It is bordered by Finland and Russia to the northeast and the Skagerrak strait to the south, on the other side of which are Denmark and the United Kingdom. Norway has an extensive coastline, facing the North Atlantic Ocean and the Barents Sea. The maritime influence dominates Norway's climate, with mild lowland temperatures on the se ...

Floating Cable-stayed Bridge
A Floating cable-stayed bridge is a type of cable-stayed bridge where the towers float on tension-leg submerged material, tethered to the seabed for buoyancy. No floating cable-stayed bridge has been made or planned yet, a floating suspension bridge has been planned in Norway. This bridge could be more stable horizontally across the bridge than floating suspension bridges, the lateral movement force from the wind and current in the water is a problem trying to be resolved by placing the tethered cables at different angles from the floating platform to the seabed.https://www.researchgate.net/publication/348972910_Dynamic_Behavior_of_a_Long-Span_Cable-Stayed_Bridge_with_Floating_Towers_after_the_Sudden_Failure_of_Tethers_and_Cables_Under_Irregular_Waves See also *List of longest cable-stayed bridge spans *List of longest suspension bridge spans * List of cable-stayed bridges in the United States *Cable-stayed suspension bridge A cable-stayed suspension bridge or CSS bridge me ...

Cable-stayed Suspension Bridge
A cable-stayed suspension bridge or CSS bridge merges the designs of cable-stayed bridges and suspension bridges. The suspension bridge's architecture is better at handling the load in the middle of the bridge, while the cable stayed bridge is better suited to handle the load closest to the tower. Combining these two architectural engineering ideas into a hybrid has been done in Istanbul with the Yavuz Sultan Selim Bridge. A bridge over the Krishna River in India has been approved in October 2022 that will be a CSS bridge design. Yavuz Sultan Selim Bridge In Turkey the Yavuz Sultan Selim Bridge over the Bosporus Strait opened in August 2016. The main span is long and is the 13th longest bridge span in the world.

Intercontinental And Transoceanic Fixed Links
A fixed link or fixed crossing is a persistent, unbroken road or rail connection across water that uses some combination of bridges, tunnels, and causeways and does not involve intermittent connections such as drawbridges or ferries. A bridge–tunnel combination is commonly used for major fixed links. This is a list of proposed and actual transport links between continents and to offshore islands. See also list of bridge–tunnels for another list of fixed links including links across rivers, bays and lakes. History Cosmopolitan Railway In 1890 William Gilpin first proposed to connect the continents by land via the Cosmopolitan Railway. Significant elements of that proposal, such as the English Channel Tunnel, have been constructed since that era. However, the improvement of the global shipping industry and advent of international air travel has reduced the demand for many intercontinental land connections.
