Torre De Collserola
Torre de Collserola () is a uniquely designed tower located on the Tibidabo hill in the Serra de Collserola, in Barcelona, Catalonia, Spain. It was designed by the architect Sir Norman Foster and by the Spanish civil engineers Julio Martínez Calzón and Manuel Julià Vilardell. This emblematic tower was built in 1991 by the construction company Cubiertas y MZOV S.A. for the 1992 Summer Olympics. It features a pod for floor space like many towers but uses guy wires for lateral support like a mast. Mainly used as a TV and radio transmitter, this futuristic design provides the highest viewpoint over the city. The top antenna reaches 288.4 m (946 ft) and the top of the pod, which has thirteen floors, reaches 152 m (499 ft). The highest point of this tower is the highest place one could be in the city of Barcelona. The tenth floor of the pod is open to the public. Events The tower has a space for event organisations, composed by a reception room and an observation d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Tower
Radio masts and towers are typically tall structures designed to support antennas for telecommunications and broadcasting, including television. There are two main types: guyed and self-supporting structures. They are among the tallest human-made structures. Masts are often named after the broadcasting organizations that originally built them or currently use them. In the case of a mast radiator or radiating tower, the whole mast or tower is itself the transmitting antenna. Terminology The terms "mast" and "tower" are often used interchangeably. However, in structural engineering terms, a tower is a self-supporting or cantilevered structure, while a mast is held up by stays or guys. Broadcast engineers in the UK use the same terminology. A mast is a ground-based or rooftop structure that supports antennas at a height where they can satisfactorily send or receive radio waves. Typical masts are of steel lattice or tubular steel construction. Masts themselves play no part in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Montjuïc Communications Tower
The Montjuïc Communications Tower ( ca, Torre de Comunicacions de Montjuïc, ), popularly known as Torre Calatrava and Torre Telefónica, is a telecommunication tower in the Montjuïc neighbourhood of Barcelona, Catalonia, Spain. It was designed by Santiago Calatrava, with construction taking place from 1989 to 1992. The white tower was built for Telefónica to transmit television coverage of the 1992 Summer Olympic Games in Barcelona. The tower is located in the Olympic park and represents an athlete holding the Olympic Flame. The base is covered with trencadís, Gaudí's mosaic technique created from broken tile shards. Sundial Because of the tower's orientation, it works also as a giant sundial, which uses the Europa Square to indicate the hour.

Modernist Architecture In Barcelona
Modernism is both a philosophy, philosophical and arts movement that arose from broad transformations in Western world, Western society during the late 19th and early 20th centuries. The movement reflected a desire for the creation of new forms of art, philosophy, and social organization which reflected the newly emerging industrial society, industrial world, including features such as urbanization, architecture, new technologies, and war. Artists attempted to depart from traditional forms of art, which they considered outdated or obsolete. The poet Ezra Pound's 1934 injunction to "Make it New" was the touchstone of the movement's approach. Modernist innovations included abstract art, the stream-of-consciousness novel, montage (filmmaking), montage cinema, atonal and twelve-tone music, divisionist painting and modern architecture. Modernism explicitly rejected the ideology of Realism (arts), realism and made use of the works of the past by the employment of reprise, incorpor ...

Communication Towers In Spain
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 universal phenomenon and a 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 meaning among entities or groups through the use of sufficiently mutually understood signs, symbols, and semiotic conventions. An important distinction is between verbal communication, which happens through the use of a language, and no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sarrià-Sant Gervasi
Sarrià-Sant Gervasi is one of the biggest districts of Barcelona. It's the district with the highest per capita income, the largest proportion of university degrees and the lowest unemployment rate. Situated on the north-west of the city, surrounded by the districts of Les Corts, Gràcia, Eixample and Horta-Guinardó and by the villages of Sant Just, Sant Feliu, Molins de Rei, and Sant Cugat. It is formed by the old villages of Sarrià (added to Barcelona in 1927), Vallvidrera (added to Sarrià in 1890), Santa Creu d'Olorda (added to Sarrià in 1916), and Sant Gervasi (" Saint Gervasius") de Cassoles (added to Barcelona in 1897). The first written document found about Sarrià dates from the year 987, and the origins of the village are a Roman colony. The old Monestir de Pedralbes belonged to the village of Sarrià, and it is now the Museo Thyssen-Bornemisza. Today, Sarrià still retains a village atmosphere, even in the middle of Barcelona, with narrow streets and small houses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Towers In Catalonia
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 languag ...

Buildings And Structures In Barcelona
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Tallest Towers
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 ...

Twaron
Twaron (a brand name of Teijin Aramid) is a Aramid, para-aramid. It is a heat-resistant and strong synthetic fibre developed in the early 1970s by the Dutch company Akzo Nobel's division Enka BV, later Akzo Industrial Fibers. The research name of the aramid, para-aramid fibre was originally Fiber X, but it was soon called Arenka. Although the Dutch para-aramid fiber was developed only a little later than DuPont's Kevlar, the introduction of Twaron as a commercial product came much later than Kevlar due to financial problems at the AKZO company in the 1970s. History This is a chronology of the development of Twaron: * In 1960s a research program starts for "Fiber X." * In 1972 the ENKA Research laboratory develops a para-aramid called Arenka. * In 1973 Akzo decides to use sulfuric acid, sulfuric acid (H2SO4) as a solvent for spinning. * In 1974 New process route was found at Akzo Research laboratory, using N-methylpyrrolidone (NMP) with a co-solvent (auxiliary solvent) with an ionic ...

Observation Tower
An observation tower is a structure used to view events from a long distance and to create a full 360 degree range of vision to conduct long distance observations. Observation towers are usually at least tall and are made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in the ancient world, as long ago as the Babylonian Empire. Observation towers that are used as guard posts or observation posts over an extended period to overlook an area are commonly called watchtowers instead. Construction and usage Observation towers are an easily visible sight on the countryside, as they must rise over trees and other obstacles to ensure clear vision. Older control rooms have often been likened to medieval chambers. The heavy use of stone, iron, and wood in their construction helps to create this illusion. Modern towers frequently have observation decks or terraces with restaurants or on the roof of mountain st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
