VIBRATION CONTROLLED BUILDING, METHOD OF CONTROLLING VIBRATION OF BUILDING, REINFORCED CONCRETE BUILDING, AND METHOD OF IMPARTING LONG PERIOD TO REINFORCED CONCRETE BUILDING
PROBLEM TO BE SOLVED: To provide a vibration controlled building which is constructed by connecting an external building having a rigid-frame structure and an internal building together by vibration control members, wherein the vibration controlled building has imparted thereto long natural period without reducing the number of columns and beams of the external building.;SOLUTION: The vibration controlled building 10 is formed of the external building 20 constructed of the rigid-frame structure, the internal building 30, and the vibration control dampers 41 connecting between the buildings 20, 30. To connect between the beam members 23 and the column members 21 in the external building 20 constructed of the rigid-frame structure, at least one of the beam member is formed such that a member end or the vicinity of the member end of the beam member 23 has a flexural rigidity smaller than the flexural rigidity at a main portion of the beam member 23.;COPYRIGHT: (C)2009,JPO&INPIT
