Abstract

Sky Tower is a skyscraper in Wrocław, Poland. Construction began in December 2007 with the demolition of the 24-story Poltegor structure, until then the tallest building in the city. Sky Tower is the tallest residential building in Poland in the category of height to roof and category of highest floor but is shorter than the Palace of Culture and Science. On the 49^th floor is a publicly accessible viewpoint. Operational Modal Analysis (OMA) of Sky Tower was done in 2012 when the tower was almost completed. No excitations with the exception of ambient excitations were used 8 eigenfrequencies and eigenforms were detected.
