The Federation Tower undergoes TsAGI aerodynamic tests
4 December 2017
The Federation Tower is a skyscraper — part of the Moscow International Business Center. The monumental building consists of two impressive towers erected on one podium uniting them into a single whole: the West Tower, with 63 floors and 243 meters high, and the East Tower, 95 floors, 374 meters high. It is the tallest residential building in Europe.
The Zhukovsky Central AeroHydrodynamic Institute (TsAGI, a member of the National Research Center “Zhukovsky Institute”) tested the Federation Tower, as well as many other high-rise structures of the Russian capital: the new Jameh congregational mosque, the Victory Monument at Poklonnaya Gora, the sculpture of V. Mukhina “Worker and Kolkhoz Woman,” and others.
The aerodynamic testing of the structure was conducted in the Moscow research complex of TsAGI in 2008. The tested objects were the two buildings and the lift shaft’s internal workings. Experiments were conducted in the oldest TsAGI wind tunnel, the T-1-2. Not only aerodynamic characteristics of wind loading, but also options for possible forms of fragility of high-rises (wind resonance, swaying, buffeting) were studied there.
The testing of large-scale models with a height of 2.5 meters was carried out at the installation through rotational vibration, simulating the dynamic behavior of the model in the direction perpendicular to the flow.
Based on the results, the experts of the Institute (jointly with specialists of the Melnikov Central Research and Design Institute of Steel Structure) made recommendations on the shape and characteristics of the mechanical vibrations in the mathematical system to prevent possible buffeting instability and swaying of the building complex.
