VIBRATION SUPPRESSION DEVICE
PROBLEM TO BE SOLVED: To provide a vibration suppression device that can securely avoid an excessively large cross section of a beam thereof, properly suppress vibration of a structure, and achieve size reduction of the whole device and reduction in manufacturing cost of the device.SOLUTION: The vibration suppression device according to the present invention includes: first and second support members 2 and 3 which have one-end parts connected to predetermined first and second regions R1 and R2 halfway on a first beam BD, extend obliquely toward a second beam BU, and have other-end parts connected to each other; and mass dampers 4 and 5 which have rotary masses 23 and 33, and are connected to the second beam BU and the other end parts of the first and second support members 2 and 3. Each of a pair of brace structures 15 and 15 provided between the first beam BD and a third beam BL has a stud 16 connected to the first region R1 or second region R2 of the first beam BD and the third beam BL, and a brace 17 connected to a joint part between the first region R1 or second region R2 of the first beam BD and a first column PL or second column PR of the third beam BL.
【課題】梁の断面の過大化を確実に回避し、構造物の振動を適切に抑制でき、装置全体の小型化及び製造コストの削減を図ることができる振動抑制装置を提供する。【解決手段】本発明の振動抑制装置は、一端部が第１梁ＢＤの途中の所定の第１及び第２部位Ｒ１、Ｒ２に連結され、第２梁ＢＵに向かって斜めに延び、他端部において互いに連結された第１及び第２支持部材２、３と、回転マス２３、３３を有し、第２梁ＢＵと第１及び第２支持部材２、３の他端部に連結されたマスダンパ４、５と、を備える。第１梁ＢＤと第３梁ＢＬの間に設けられた一対のブレース構造１５、１５は、それぞれ、第１梁ＢＤの第１部位Ｒ１又は第２部位Ｒ２と第３梁ＢＬに連結された間柱１６と、第１梁ＢＤの第１部位Ｒ１又は第２部位Ｒ２と第３梁ＢＬの第１柱ＰＬ又は第２柱ＰＲとの接合部とに連結されたブレース１７を有する。【選択図】図９
