DAMPING STRUCTURE OF BUILDING FRAME
To provide a damping structure of a building frame capable of suppressing effectively twisting that occurs on a building frame while efficiently suppressing vibration against input vibration to the building frame.SOLUTION: The damping structure is a structure for suppressing vibration against input vibration to a building frame 1 built with a lower part 1a fixed in the ground G. On both sides of the building frame, a pair of sub-frames 2 is provided along the height direction of the building frame, in which the top part 2a is rigidly connected to the top part 1b of the building frame, and the lower part 2b is spaced upward from the ground to form a vibration system integral with the building frame. The sub-frames are supported being suspended from the top of the building frame, and the stiffness of the top of the building frame is set to a higher rigidity than other parts of the building frame. In an attachment area F set in each gap S between each of the lower parts of the sub-frames and the lower part of the building frame, a vibration-damping device is oriented around the rigid center R1 of the building frame on a plane along the ground plane E with one end connected to the building frame and the other end connected to the subframe.SELECTED DRAWING: Figure 1
【課題】振動入力に対して建物架構を効率よく制振すると共に、建物架構に生じるねじれを効果的に抑制することが可能な建物架構の制振構造を提供する。【解決手段】地盤Ｇに下部１ａが固定されて構築された建物架構１を、振動入力に対して制振するための制振構造であって、建物架構の両側に、建物架構の高さ方向に沿って設けられ、当該建物架構の頂部１ｂに頂部２ａが剛接合され、下部２ｂが地盤から上方に間隔を隔てられて、建物架構と一体の振動系を形成する一対の副架構２を備え、これら副架構は、建物架構の頂部から吊り下げ支持され、建物架構の頂部の剛性は、当該建物架構の他の部分よりも高い剛性に設定され、これら副架構の下部それぞれと建物架構の下部との各隙間Ｓに設定される取り付け領域Ｆには、地盤面Ｅに沿う平面における建物架構の剛心Ｒ１周りに沿う向きに配置して、建物架構に一端を連結し他端を副架構に連結して、振動減衰装置が設けられる。【選択図】図１
