TsAGI’s Centenary in History: Federation Tower high-rise complex

18 November 2019

In November 2017 the construction of the Federation Tower high-rise complex, a flagship project of the Moscow International Business Center Moscow City, was completed. An important role in the aerodynamic research was played by the specialists of the Central Aerohydrodynamic Institute named after Professor N.E. Zhukovsky (part of the National Research Center Zhukovsky Institute NRC).

In 2008 TsAGI’s Moscow Research Complex tested the two buildings and the elevator shaft of the complex in TsAGI’s oldest T-1-2 WT to examine both the aerodynamic characteristics of wind loading and the parameters of possible instability modes of high-altitude buildings (buffeting, wind resonance, galloping, etc.). The tests of 2.5 meter model were performed on an angular oscillations unit that imitated the model dynamic behavior in the direction perpendicular to the flow.

Based on the results, the scientists of the Institute (in cooperation with the specialists of Melnikov Central Research and Design Institute of Steel Structures) produced recommendations on the image and characteristics of the system of the mechanical vibration absorbers to avoid possible instability modes like buffeting and galloping of the buildings.

TsAGI’s experiment database is used not only to analyze the models of aircraft but also bridges, buildings, and monuments. Such types of experiments have been conducted in the institute since 1925, and one of the first test objects were TsAGI’s building in Radio Street and the statue of Lenin for the Palace of the Soviets project. Nowadays the testing is an important stage of any high-rise construction.

The Moscow Complex tested the models of the majority of Moscow’s buildings taller than 70 meters, for instance, the Victory Monument on Poklonnaya Gora, the Worker and Kolkhoz Woman sculpture, Moscow Cathedral Mosque, etc.

One of the Federation towers called Vostok (East) reaches 373.7 meters and is Europe’s second tallest building after Lakhta Center in St. Petersburg, but has a higher number of floors.
