Abstract:

This paper presents an overall view of the wind resistant design and response control of the tall buildings in Japan, the Crystal Tower in Osaka and the Landmark Tower in Yokohama. The wind loads are dominant in both buildings, and the special considerations are given to the human discomfort due to the building motion induced by strong winds. The Crystal Tower completed in 1990 is the first tall building with a tuned mass damper in Japan. The Landmark Tower, tallest in Japan, is now under construction and will have another tuned active damper. Both dampers can reduce the building motion due to strong winds by 50%.
