Ōta River Bridge
The Ōta River Bridge (, also rendered in rōmaji as Otagawaohashi, also called Otagawa Bridge or Otagawa Ohashi Bridge) is a bridge on the Ōta River in Hiroshima, Japan. It is the southernmost of all the crossings of the Ōta River and carries Route 3 (the Hiroshima Minami Route) of the Hiroshima Expressway (urban expressway), Hiroshima Expressway. Construction A decision to build a bridge as part of the expressway system was made in 2004. A Architectural design competition, design competition committee was formed in late 2008 and received entries from 18 Japanese and three international firms. The winning design by Kenichi Nishiyama of collaborating with Yoko Kabaki, Akiyoshi Nii, and Hitoshi Okamura, was selected in July, 2009. The bridge was built by Shimizu Corporation and finished in 2014. The bridge design had to comply with height restriction laws due to its proximity to Hiroshima–Nishi Airport. The bridge, a composite prestressed concrete continuous rigid frame box g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Height Restriction Laws
Height restriction laws are laws that restrict the maximum height of structures. There are a variety of reasons for these measures. Some restrictions serve aesthetic values, such as blending in with other housing and not obscuring important landmarks. Other restrictions may serve a practical purpose, such as height restrictions around airports for flight safety. Height restriction laws for housing have become a source of contention by restricting housing supply, increasing housing costs, and depressing land values. Asia China New building regulations that came in force in 2020, limited the height of buildings on cities depending on population in China. Cities with less than 3million population cannot have structures rising above ; cities with populations greater than 3million can have buildings up to a height of . Buildings are capped at on the Shenzhen Bay area due to its proximity to Shenzhen Bao'an International Airport. A similar height restriction also applies in Wuhan, w ...

Bridges In Hiroshima Prefecture
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or railway) without blocking the path underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge, dating from the 13th century BC, in the Peloponnese is one of the oldest arch bridges in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the word ''bridge' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch Bridges In Japan
An arch is a curved vertical structure spanning an open space underneath it. Arches may support the load above them, or they may perform a purely decorative role. As a decorative element, the arch dates back to the 4th millennium BC, but structural load-bearing arches became popular only after their adoption by the Ancient Romans in the 4th century BC. Arch-like structures can be horizontal, like an arch dam that withstands the horizontal hydrostatic pressure load. Arches are usually used as supports for many types of vaults, with the barrel vault in particular being a continuous arch. Extensive use of arches and vaults characterizes an arcuated construction, as opposed to the trabeated system, where, like in the architectures of ancient Greece, China, and Japan (as well as the modern steel-framed technique), posts and beams dominate. Arches had several advantages over the lintel, especially in the masonry construction: with the same amount of material it can have larger ...

Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially prestressed (Compression (physics), compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." It was patented by Eugène Freyssinet in 1928. This compression is produced by the Tension (physics), tensioning of high-strength ''tendons'' located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire Wire rope, strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concre ...

Hiroshima–Nishi Airport
was an airport in Nishi Ward, located southwest of Hiroshima City, Japan. The airport closed in November 2012, with the northern portion of the site continuing operation as Hiroshima Heliport (広島ヘリポート). History Hiroshima's first airport, , opened on a nearby island in Naka-ku, Hiroshima in 1940. It was largely destroyed during the atomic bombing of Hiroshima in 1945, but was used during the occupation of Japan as a radar base by the Royal Australian Air Force 111 Mobile Fighter Control Unit, and through the 1950s as a landing field for gliders and single-engine piston aircraft. Hiroshima Airport era Following the end of World War II, the Japanese government approved a plan for a new airport in a location which could take advantage of Hiroshima's natural river topography to keep aircraft from flying over residential areas. Hiroshima Airport opened on September 15, 1961, and was initially managed by the Ministry of Transport. Its passenger terminal was the sec ...

Ōta River
is a river in Hiroshima Prefecture, Japan. Geography Its main stream originates in (1,339 m) and empties, through a flood-control channel, into the Seto Inland Sea. The river is one of the major rivers in the prefecture and descends through steep topography, with hydroelectric power plants situated along the river. The Ōta has numerous tributaries and branches into the delta area of Hiroshima which comprises the Tenma, Kyūōta/Honkawa, Motoyasu, Kyōbashi, and Enkō rivers. Originally, the Ōta River passes through the western side of Aioi Bridge which was the aiming point for the atomic bombing of Hiroshima. A flood-control channel was built along the former Yamate river in the late 1960s, which became the main passageway of the Ōta River. The original passageway of the Ōta is now known as the Kyūōta River (旧太田川, ''Kyūōta-gawa'', lit. "Old Ōta") or Honkawa River (本川, ''Honkawa''). Ōta River runs through the municipalities of Hatsukaichi, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Architectural Design Competition
An architectural competition is a type of design competition, in which an entity that intends to build new work, or is just seeking ideas, invites architects to submit design proposals. The winning scheme is usually chosen by an independent panel of design professionals and stakeholders (such as government and local representatives, the leadership of a cultural institution, etc.). This process is often used to generate new ideas for building and/or landscape design, stimulate public debate, generate publicity for the project and the commissioning entity, and help emerging designers gain exposure (and potentially win commissions that might be out of reach to them otherwise). Architectural competitions are often, though not exclusively, used to award commissions for public buildings: In some countries, rules for tendering public building contracts stipulate some form of open architectural competition.
