National Theatre: performance without microphone

Many Beijing residents in his spare time, dream place, than to just open the near National Grand Theatre. From 2007, December 22, at the opening of the National Theater, the International Festival ticket sales has passed. According to the ticket office staff, in January of this year's tickets sold out, fortunately, in February and March of tickets already on sale. In fact, the opening of the International Festival of tickets is not cheap, for many wage-earners, considered a luxury consumption. But as a teacher friends said: "the National Grand Theatre concert, not only to Seiji Ozawa, Lang Lang, Catherine · Alba, and other stars that participated in the musical feast, but also close to experience a high-tech's charm is your point, and value. "Indeed, the building of National Theater, uses many high-tech, it can be said that the National Grand Theatre in the world of work in building technology, is a high-tech makes the" egg ". So, what the National Grand Theatre in which high-tech? you don't worry, listen to me slowly. Why don't exotic frozen Lakes National Grand Theatre, just like a floating on the water "eggshell", especially at night, illuminated by the national theatre of reflection in the water, like a star in the dark shiny pearls, magnificent. We have to thank the National Grand Theater of the Chief Designer, design guru Paul France · Andrew, is his romantic temperament that we saw a great landscape. January is the coldest season in Beijing, the cold ground, freezing temperatures. But to the National Theater of people will find that surround the Lake Theatre is popple, what is? this is original, engineering and technical personnel approach called the "Central liquid cooling and environmental system" of the device, the device's basic principle is to draw from the underground temperature is 15 degrees of ground water and pulled from the artificial lake in the pipeline in the loop, two pipes on the wall of the body is solid spiral interlaced together, this will make the pond area of 35000 square meters of the Lake remained at a constant temperature above zero, not because of the direct exchange of water waste, pollution caused by. As a result, the TAM achieved year round the Lake of "spring water" lingers — not icy winter, summer or long algae. How the egg shell tie-up many people National Grand Theatre affectionately known as "eggshell", in fact, this "eggshell" just national Grand Theater of the dome, by 148 of radial pin huge arc steel trusses consisting of skeletons and mounted on the skeleton of the 2 million pieces of titanium slabs, 1200 more transparent glass panels assembled block. The big dome is the largest of our span steel structure building shell, it is said that can take over Games Beijing workers ' Stadium all cover live. This steel sky, there will be a magnificent feeling, but surprisingly, such enormous steel structure intermediary but no pillars support, that is, experience an earthquake, storm, natural disaster, the total weight of 1.2 tons of large dome to completely rely on their mechanical structure of the system to ensure safety and stability. To do this is not easy. Chief Designer Paul · Mr. Andrew had dome security issues design a package to the bottom of the dome to install multiple rubber bearings, the use of materials of rubbers to deformation characteristics, to buffer the outside world brought great theater of unsafe. It is said that France's Arc de Triomphe is similar as damping rubber bearings with Jack, architectural method replace. But the problem is that the rubber bearing service life 30 years theatre design service life of 100 years. The big dome can be like the Arc de Triomphe, France with Jack up replacement rubber bearing? country without this precedent, the experts on this way is not very sure. Is there a better way?, after much discussion, the Group decided to look for other support materials. After precision measurement and experimentation, ultimately decided to use the same vibration reduction function to replace the rubber bearing steel material avoids the original design every 30 years is going to replace the damping bracket trouble, also make the big "eggshell" possess a Tai Chi master skills, can be used for the theory, deflected the easy solution of skill from the outside world. Performance night without a microphone, if seen from Beijing Chang'an 0796 Grand Theatre, the big shell as slowly opened the stage curtain, magnificent rest Hall of audience and the Opera House, theater, concert hall, three half-hidden half out of the theatre building unfolds in front of you, this visual effect is extremely exciting.
