Malmskillnadsbron 2017-09-11 13
Malmskillnadsbron (''The Malmskillnad Bridge'') is an arch bridge in central Stockholm, Sweden. It takes the street Malmskillnadsgatan over Kungsgatan flanked on its east side by two Art Deco towers called Kungstornen. For an explanation of ''Malmskillnad'', see Malmskillnadsgatan. Built in connection with the excavation of Brunkebergsåsen for Kungsgatan, Malmskillnadsbron was inaugurated in 1911, one year after the completion of the parallel bridge taking Regeringsgatan over Kungsgatan, circumstantially called ''Regeringsgatans viadukt över Kungsgatan'', "The Bridge of Regeringsgatan over Kungsgatan", and, more popularly, ''Regeringsgatans bro'', Bridge of Regeringsgatan. The bridge is a reinforced concrete three-hinged arch bridge dressed in granite slabs. The vault is entirely filled and supported on both sides by concrete walls perpendicular to Kungsgatan. The span is 24 metres, the width of 9.05 metres between the railings, and the bridge has a 5.55 metres wide roadway ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bridge Of Regeringsgatan
Regeringsgatans bro (''The bridge of Regeringsgatan'') or more correctly Regeringsgatans viadukt över Kungsgatan (''Bridge of Regeringsgatan over Kungsgatan'') is a bridge in central Stockholm, Sweden, taking the street Regeringsgatan over Kungsgatan. It was inaugurated in 1910. Description The bridge is a combined arch and beam bridge made of three reinforced concrete beams vaulted underneath and resting on two supports. Its vertical sides dressed in granite, the bridge is 11.1 metres wide with a 6.7 metres wide roadway. In contrast to the parallel bridge Malmskillnadsbron, the Bridge of Regeringsgatan is using three arches to cross Kungsgatan; the central span, 14.5 metres in length, passes over the roadway below; while the two spans on it sides, 5.5 metres in length, passes over the pavements of Kungsgatan. The unwieldy intermediate supports makes effective usage of the street width below impossible, and substituting the present construction have therefore been suggested. ...

Bridges In Stockholm
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way 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, and 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 still in existence and use. Etymology The ''Oxford English Dictionary'' traces the origin of the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sveavägen
Sveavägen is a major street in Stockholm, Sweden. Sveavägen originates at Sergels torg in the city district of Norrmalm, and goes north through the Vasastan district toward the border to Solna Municipality and the Haga Park. It is often known as the busiest road in Sweden. Sveavägen follows a straight line from Sergels torg up to Sveaplan and Wenner-Gren Center where it takes a sharp left turn until the junction at Norrtull where it becomes Norra Stationsgatan. Between Rådmansgatan and Hötorget stations, the Green line of the Stockholm metro runs underneath Sveavägen. Both stations have access from the street. History Prime Minister Olof Palme was assassinated on 28 February 1986 at the corner Sveavägen and Tunnelgatan. Notable buildings Notable buildings located on Sveavägen include: * Stockholm school of economics - a private business school located in the city district Vasastan at Sveavägen 65. The main building of the school was designed by Ivar Ten ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Bridges In Stockholm
This is a list of some of the most notable bridges and viaducts in Stockholm, starting with those located closest to the city centre. Many more bridges and viaducts could, of course, be added, including those on the rail and motorway networks, and the many grade-separated junctions in the suburbs which are a product of postwar city planning. Historical * Sveabron (where present-day Odengatan passes over Sveavägen) * Nybro or Stora Ladugårdslandsbron (across today's Berzelii Park) * Näckströms bro (connecting Norrmalm and Blasieholmen) Additionally, during the cold winters in the 19th century, ice in the city harbour made it necessary to replace ferries by temporary pontoon bridges sometimes more than 300 m in length.

Cobblestone
Cobblestone is a natural building material based on cobble-sized stones, and is used for pavement roads, streets, and buildings. Setts, also called Belgian blocks, are often casually referred to as "cobbles", although a sett is distinct from a cobblestone by being quarried or shaped to a regular form, whereas cobblestone is generally of a naturally occurring form and is less uniform in size. Use in roading Cobblestones are typically either set in sand or similar material, or are bound together with mortar. Paving with cobblestones allows a road to be heavily used all year long. It prevents the build-up of ruts often found in dirt roads. It has the additional advantage of immediately draining water, and not getting muddy in wet weather or dusty in dry weather. Shod horses are also able to get better traction on stone cobbles, pitches or setts than tarmac or asphalt. The fact that carriage wheels, horse hooves and even modern automobiles make a lot of noise when rolli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is ...

Hinge
A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation: all other translations or rotations being prevented, and thus a hinge has one degree of freedom. Hinges may be made of flexible material or of moving components. In biology, many joints function as hinges, like the elbow joint. History Ancient remains of stone, marble, wood, and bronze hinges have been found. Some date back to at least Ancient Egypt. In Ancient Rome, hinges were called cardō and gave name to the goddess Cardea and the main street Cardo. This name cardō lives on figuratively today as "the chief thing (on which something turns or depends)" in words such as ''cardinal''. According to the OED, the English word hinge is related to '' hang''. Door hinges ; Barrel hinge: A barrel hinge consists of a sectional barrel (the ...

Reinforced Concrete
Reinforced concrete (RC), also called reinforced cement concrete (RCC) and ferroconcrete, is a composite material in which concrete's relatively low tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel bars (rebar) and is usually embedded passively in the concrete before the concrete sets. However, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure. Modern reinforced concrete can contain varied reinforcing materials made ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arch Bridge
An arch bridge is a bridge with abutments at each end shaped as a curved arch. Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today. History Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace. The well-preserved Hellenistic Eleutherna Bridge has a triangular corbel arch. The 4th century BC Rhodes Footbridge rests on an early voussoir arch. Although true arches were already known by the Etruscans and ancient Greeks, the Romans were – as with the vault and the dome – the first to fully realize the potential of arches for bridge construction.
