The l argest broadcasting centre in C entral Asia for more than 20 years presents itself united, night and day acting technological system. The most modern production, commutation and telecommunication equip ments of leadinging companies of the world and more than one hundred high qualified specialist s provide TV and radio broadcasting programs for Tashkent city and Tashkent region .
In 2005 there was celebrated 20 years of Tashkent TV Tower . The c onstruction of Tashkent TV Tower was started in 1978 on the project s of architect s Y u .L.S emashko , N.G.Terzieva-Carukova and engineer s E.P.Morozova, M.D.Musheeva. The c onstruction was conducted by the specialist s of “ Vysotstroy ” trust and MU-25 Leningrad Division of “ Glavstalkonstrukc y” , as well as more then 30 building and erection subcontract organization s during seven years and it was finished on January 1985. On January 15 200 5 was p assed 20 years since the moment of giving the project “ Tashkent TV Tower H -3 7 5m ” (so it is named exactly in official document s ) for exploitation .
Some parameters of the TV Tower are following :
Height - 375 metres .
At the time of the starting exploitation Tashkent TV Tower was the fourth highest tower in the world. At present time after more then twenty years Tashkent TV Tower is on the ninth honourable place in the world and it is a member of World Federation of Great T ower s . Having the height of 375 metres , it is t he high est tower in Central Asia. Be side s the size s , the TV Tower is advantageously distinguish ed with unique architectral, engineering and artistic decisions, despite the fact that it is built in the zone with high seismic activity. The u nique engineering decision has allowed to execute in metal (apropos, metals of german plant Krupna , processed by C h elyabinsk pipe-rolling plant) complex architectral composition of latticed and utter wall constructions .
The Tower consists of three constructive parts united horizontal hinge connections : central stem, lattice d framework and tripod. The c entral stem of antenna and lift part is the pivot of lattice d cylindrical framework with the height of 220 m , which in turn, is inserted inside the glass of 100 m tripod (the tray legs), was fixed on it by antenna part, lift mine s , technological, servicing and civil premiseses and made in the glass of the central foundation with supporting plate with diamet er of 32 m . L egs of the tripod are sealled in three separate stand ing peripheral foundation s by diameter 15 m each. Foundations of the T ower connected between their self with flexible connections – iron concrete tape s , on which were installed pillars and wall s of the technical building. Between latticed framework and the glass of the tripod on the height of 94,5 m were installed radial connections , hinge fixed in both sides by circula r belt of both framework and glass.
Performed thereby unique architectural engineering decisions of the constructive part of the T ower are capable to make joint work in windy and seismic influence .The T ower as a whole has raised spares of filling and spending elastic energy without destruction. Herewith, the hinge connections transfer horizontal reactions on more hard external constructive parts, but do not prevent the mutual warm-up offsets under different solar heating utter wall and latticed parts. This dignity of constructive decisions ( “ Vanka- vstanka” principle) particularly is important under seismic region of the construction in 9 points . In two marks - 100 and 220 m - a stem of the T ower is belted by multi-story (each with 5 floors) premises - servicing , technical, meteorological and restaurant. From the mark 223,5 m till 375 m is antenna part of the T ower, consisting of pipes of the variable diameter from 4 m till 0,72 m crowning with the flag.
The c onstructive p e cul i arity of the antenna part is that vertical load from it is transmitted on the marks of 117 - 123 m , perception of horizontal loads occurs on the marks of 209,8 and 220,4 m by the hinge section s located on perimeter and connecting four metre s stem with latticed stem of the T ower. Considering a big construction importance of the Tower's silhouette and technical peculiarities (minimum lengths of feeder s between transmitter s and antenna s ), the technical building projected with unique two-story building with cellar and has a form of truncated on the corners equilateral triangle , composite ly connected with architecture of the Tower's stem having 3 sloping tilts .
