Abstract
This paper presents the setup, methodology and results of wind tunnel aeroelastic model tests of a tall residential building planned in the inner centre of Warsaw, Poland. The tests were performed at the aerodynamic tunnel of Wind Engineering Laboratory of Cracow University of Technology. The building can be characterised as a super-slim building, with its cross-section varying along the height into a distinctive narrowing in the lower part, causing the upper part to effectively work as a cantilever. The aeroelastic model tests aimed to assess the level of vibrations accelerations of the building’s top floors, which might be uncomfortable or harmful for its residents. The results showed that the building is susceptible to vibrations with accelerations close to the comfort threshold, but the comfort and safety criteria are fulfilled. While wind-induced vibrations might often be less crucial for the structural design, this experiment shows that it can be vital to perform a vibrational comfort assessment for such slender structures, even if their height alone would not suggest so.
