Kherson TV Tower
Kherson TV Tower ( uk, Херсонська телевежа "Kherson TV Tower") was a tall steel space framed truss communications tower located in the Ukrainian city of Kherson. The building was uniquely built, having been built by using the cross bracing system. The tower was a truss TV tower, specifically, a Vierendeel truss tower, wherein a structure's members are not triangulated but form rectangular openings instead (see Vierendeel Truss). The tower had an antenna that measured and a roof that measured . The tower possessed a total height of , and was the tallest structure in the Kherson Oblast. During the Russian invasion of Ukraine, the tower was destroyed by retreating Russian forces on 10 November 2022. History Although the exact date of the commencing of the tower's construction is unknown, construction of the Kherson TV Tower was begun in 1991 and finished after 14 years, to be exact, in 2005, in the city of Kherson, in Ukraine.

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 ...

Towers In Ukraine
A tower is a tall structure, taller than it is wide, often by a significant factor. Towers are distinguished from masts by their lack of guy-wires and are therefore, along with tall buildings, self-supporting structures. Towers are specifically distinguished from buildings in that they are built not to be habitable but to serve other functions using the height of the tower. For example, the height of a clock tower improves the visibility of the clock, and the height of a tower in a fortified building such as a castle increases the visibility of the surroundings for defensive purposes. Towers may also be built for observation, leisure, or telecommunication purposes. A tower can stand alone or be supported by adjacent buildings, or it may be a feature on top of a larger structure or building. Etymology Old English ''torr'' is from Latin ''turris'' via Old French ''tor''. The Latin term together with Greek τύρσις was loaned from a pre-Indo-European Mediterranean langua ...

Kyiv TV Tower
The Kyiv TV Tower ( uk, Телевізійна вежа, translit=Televiziyna vezha) is a lattice metal tower on Oranzhereina Street, Kyiv, Ukraine, and is the tallest structure in the country. The tower was built in 1973 while Kyiv was the capital of Ukrainian SSR. The tower was the tallest freestanding metal structure in the world until being surpassed by the Tokyo Skytree in 2012. It is used for radio and television broadcasting and is not open to the public. History The tower was first designed for Moscow, then the Soviet capital. But Moscow authorities preferred a more "solid" type of tower, which was eventually built ( Ostankino Tower). Later, when Kyiv needed its own tower, the project was reintroduced. The Soviet government ordered the engineers to shorten the tower by almost 30%, so as not to be as tall as the Moscow one. Location The tower was built on top of the Jewish cemetery in Lukianovka. The cemetery was officially closed in 1966 and Jewish families were g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Tallest Towers In The World
Several extant building fulfill the engineering definition of a tower: "a tall human structure, always taller than it is wide, for public or regular operational access by humans, but not for living in or office work, and are ''self-supporting'' or ''free-standing'', which means no guy-wires for support." This definition excludes continuously habitable buildings and skyscrapers as well as radio and TV masts. Also excluded because they are not designed for public or regular operational access are bridge towers or pylons, wind turbines, chimneys, transmission towers, sculptures and most large statues and obelisks. Towers are most often built to use their height for various purposes, and can stand alone or as part of a larger structure. Some common purposes are for telecommunications, and as a viewing platform. The Tokyo Skytree, completed in February 2012, is , making it the tallest tower, and third-tallest free-standing structure in the world. Entirely self-supported towers ...

2022 Russian Invasion Of Ukraine
On 24 February 2022, in a major escalation of the Russo-Ukrainian War, which began in 2014. The invasion has resulted in tens of thousands of deaths on both sides. It has caused Europe's largest refugee crisis since World War II. An estimated 8 million Ukrainians were displaced within their country by late May and 7.8 million fled the country by 8 November 2022, while Russia, within five weeks of the invasion, experienced its greatest emigration since the 1917 October Revolution. Following the 2014 Ukrainian Revolution, Russia annexed Crimea, and Russian-backed paramilitaries seized part of the Donbas region of south-eastern Ukraine, which consists of Luhansk and Donetsk oblasts, sparking a regional war. In March 2021, Russia began a large military build-up along its border with Ukraine, eventually amassing up to 190,000 troops and their equipment. Despite the build-up, denials of plans to invade or attack Ukraine were issued by various Russian gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cross Bracing
In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing is usually seen with two diagonal supports placed in an X-shaped manner. Under lateral force (such as wind or seismic activity) one brace will be under tension while the other is being compressed. In steel construction, steel cables may be used due to their great resistance to tension (although they cannot take any load in compression). The common uses for cross bracing include bridge (side) supports, along with structural foundations. This method of construction maximizes the weight of the load a structure is able to support. It is a usual application when constructing earthquake-safe buildings. Cross bracing can be applied to any rectangular frame structure, such as chairs and bookshelves. Its rigidity for two-dimensional grid structures can be analyzed mathematically as an instance of the grid bracing problem. Cross bracing may employ full d ...

Communication
Communication (from la, communicare, meaning "to share" or "to be in relation with") is usually defined as the transmission of information. The term may also refer to the message communicated through such transmissions or the field of inquiry studying them. There are many disagreements about its precise definition. John Peters argues that the difficulty of defining communication emerges from the fact that communication is both a Universality (philosophy), universal phenomenon and a Communication studies, specific discipline of institutional academic study. One definitional strategy involves limiting what can be included in the category of communication (for example, requiring a "conscious intent" to persuade). By this logic, one possible definition of communication is the act of developing Semantics, meaning among Subject (philosophy), entities or Organization, groups through the use of sufficiently mutually understood signs, symbols, and Semiosis, semiotic conventions.

Lattice Tower
A lattice tower or truss tower is a freestanding vertical framework tower. This construction is widely used in transmission towers carrying high voltage electric power lines, in radio masts and towers (a self-radiating tower or as a support for aerials) and in observation towers. Its advantage is good shear strength at a much lower weight than a tower of solid construction would have as well as lower wind resistance. In structural engineering the term ''lattice tower'' is used for a freestanding structure, while a ''lattice mast'' is a guyed mast supported by guy lines. Lattices of triangular (3-sided) cross-section are most common, particularly in North America. Square (4-sided) lattices are also widely used and are most common in Eurasia. Lattice towers are often designed as either a space frame or a hyperboloid structure. Before 1940, they were used as radio transmission towers especially for short and medium wave. Occasionally lattice towers consisting of wood were utilized. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
