description PROBLEM TO BE SOLVED: To use an internal cylinder as a mass body of passive vibration control construction, form the weight of the internal cylinder as relatively lightweight necessary for vibration control to make lightweight the whole cylindrical tower body and to provide vibration control construction capable of simplifying bearing construction thereof by only bearing the internal cylinder on the top of an external cylinder. SOLUTION: Vibration control construction of a cylindrical tower body is constituted of an external cylinder 14 erected from the foundation 12 and an internal cylinder 16 provided to the inside of the external cylinder 14 in a state to separate it from the foundation and hung down to the top 14a of the external cylinder 14 in a state capable of being oscillated. The internal cylinder 16 is borne on the external cylinder 14 through springs 18 and damping members 20 arranged in parallel with each other, and a vibration system constituted of the springs 18, damping members 20 and mass of the internal cylinder 16 is synchronized with a natural period of the external cylinder 14.
