Oymyakon-russie-

The coldest village in the world

Discover Oymyakon, a charming village located in the north-east of Russia, where temperatures can reach up to -70 degrees.

With a pleasant average of -50 ° C generally recorded in January, this village is a place inhabited permanently despite its conditions which are the most extreme of the planet. Totally cut off from the world, he lives there 500 inhabitants.


Only one way leads to the village, the inhabitants feed on the central market which allows to eat meat and fish.


Here the amenities are not as well established as at home. With the gel it is almost impossible to do plumbing, water is scarce and toilets are often located outside the dwellings. Most households, not benefiting from modern conveniences, heat themselves either with coal or with wood fires.


In May, temperatures rise to 2.7 ° C during the day and -15 ° C at night. Not surprisingly, these Russians are accustomed to the icy cold ...


The photographer Amos Chapple went there to capture the daily life of the inhabitants

Cold-Formed Steel design : Structural Steel

Cold-formed steel framing is a durable, reliable and cost-effective option for low-rise and mid-rise building projects. It typically refers to light-frame construction where the vertical and horizontal structural elements are primarily formed by a system of repetitive framing members. The framing members are typically spaced at 16 or 24 inches on center, with spacing variations lower and higher depending on the loads and coverings.
Wall members are typically vertical lipped channel "stud" members, which fit into unlipped channel "track" sections at the top and bottom. Similar configurations are used for both floor joist and rafter assemblies, but in a horizontal application for floors, and a horizontal or sloped application for roof framing. Additional elements of the framing system include fasteners and connectors, braces and bracing, clips and connectors. Cold-formed steel floor and roof trusses are also available for cold-formed steel framing applications.
                             
This section presents information on the design of structural members that are cold-formed to cross 
section shape from sheet steels. Cold-formed steel members include such products as purlins and girts for the construction of metal buildings, studs and joists for light commercial and residential construction, supports for curtain wall systems, formed deck for the construction of floors and roofs, standing seam roof systems, and a myriad of other products. These products have enjoyed significant growth in recent years and are frequently utilized in some shape or form in many projects today. Attributes such as strength, light weight, versatility, non-combustibility, and ease of production, make them cost effective in many applications. This figure shows cross sections of typical products
