Tretten Bridge
Tretten Bridge was a road bridge in Tretten, Øyer, Norway that carried county road 254 over Gudbrandsdalen and the E6 road. The bridge was a truss bridge in glulam and steel and was opened on 15 June 2012. It collapsed on the morning of 15 August 2022, after only ten years and two months in operation. Permission was given for a temporary replacement bridge in October 2022, on the condition that work above the waterline is finished before the spring flood in April 2023. Construction There were two types of beams used for the trusses on the bridge: glued laminated timber beams were slanted, while the steel beams were vertical; weathering steel was used. The bridge replaced a steel truss bridge built in 1895 at the same location. The pier on the west side from the original bridge was in good condition and was used again after reinforcement. The new bridge was a truss bridge with two lanes and asphalt pavement. The upper and lower girders, and angle and cross braces, were made of ...

Gudbrandsdalen
Gudbrandsdalen (; en, Gudbrand Valley) is a valley and traditional district in the Norwegian county of Innlandet (formerly Oppland). The valley is oriented in a north-westerly direction from Lillehammer and the lake of Mjøsa, extending toward the Romsdalen valley. The river Gudbrandsdalslågen (Lågen) flows through the valley, starting from the lake Lesjaskogsvatnet and ending at the lake Mjøsa. The Otta river which flows through Otta valley is a major tributary to the main river Lågen. The valleys of the tributary rivers such as Otta and Gausa (Gausdal) are usually regarded as part of Gudbrandsdalen. The total area of the valley is calculated from the areas of the related municipalities. Gudbrandsdalen is the main valley in a web of smaller valleys. On the western (right hand) side there are long adjacent valleys: Ottadalen stretches from Otta village, Gausdal some from Lillehammer and Heidal some from Sjoa. Gudbrandsdalen runs between the major mountain ranges of Norw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glulam
Glued laminated timber, commonly referred to as glulam, is a type of structural engineered wood product constituted by layers of dimensional lumber bonded together with durable, moisture-resistant structural adhesives so that all of the grain runs parallel to the longitudinal axis. In North America, the material providing the laminations is termed ''laminating stock'' or ''lamstock''. History The principles of glulam construction are believed to date back to the 1860s, in the assembly room of King Edward VI College, a school in Southampton, England. The first patent however emerged in 1901 when Otto Karl Freidrich Hetzer, a carpenter from Weimar, Germany, patented this method of construction. Approved in Switzerland, Hetzer’s patent explored creating a straight beam out of several laminations glued together. In 1906 he received a patent in Germany for curved sections of glulam. Other countries in Europe soon began approving patents and by 1922, glulam had been used in 14 co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

Weathering Steel
Weathering steel, often referred to by the genericised trademark COR-TEN steel and sometimes written without the hyphen as corten steel, is a group of steel alloys which were developed to eliminate the need for painting, and form a stable rust-like appearance after several years' exposure to weather. U.S. Steel (USS) holds the registered trademark on the name COR-TEN. The name COR-TEN refers to the two distinguishing properties of this type of steel: corrosion resistance and tensile strength. Although USS sold its discrete plate business to International Steel Group (now ArcelorMittal) in 2003, it still sells COR-TEN branded material in strip-mill plate and sheet forms. The original COR-TEN received the standard designation A242 (COR-TEN A) from the ASTM International standards group. Newer ASTM grades are A588 (COR-TEN B) and A606 for thin sheet. All alloys are in common production and use. The surface oxidation of weathering steel takes six months, but surface treatmen ...

Dagsavisen
''Dagsavisen'' is a daily newspaper published in Oslo, Norway. The former party organ of the Norwegian Labour Party, the ties loosened over time from 1975 to 1999. It has borne several names, and was called ''Arbeiderbladet'' from 1923 to 1997. Eirik Hoff Lysholm is editor-in-chief. The newspaper depends on economic support from the Norwegian Government. History ''Dagsavisen'' was established by Christian Holtermann Knudsen in 1884 under the name ''Vort Arbeide'' ('Our Work' in archaic Riksmål), and was affiliated with the trade union center ''Fagforeningernes Centralkomité''. Holtermann Knudsen also had to establish his own printing press since the existing printing presses did not want to be affiliated with a labourer's newspaper. The fledgling project was marred by economic problems, and the burden of writing, editing, and printing lay chiefly on Knudsen. In 1885 the newly founded association ''Socialdemokratisk Forening'' formally took over the newspaper. The name was chan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Storting
The Storting ( no, Stortinget ) (lit. the Great Thing) is the supreme legislature of Norway, established in 1814 by the Constitution of Norway. It is located in Oslo. The unicameral parliament has 169 members and is elected every four years based on party-list proportional representation in nineteen multi-seat constituencies. A member of Stortinget is known in Norwegian as a ''stortingsrepresentant'', literally "Storting representative". The assembly is led by a president and, since 2009, five vice presidents: the presidium. The members are allocated to twelve standing committees as well as four procedural committees. Three ombudsmen are directly subordinate to parliament: the Parliamentary Intelligence Oversight Committee and the Office of the Auditor General. Parliamentarianism was established in 1884, with the Storting operating a form of "qualified unicameralism", in which it divided its membership into two internal chambers making Norway a de facto bicameral parliament ...
