VIBRATION CONTROL STRUCTURE OF BUILDING

PROBLEM TO BE SOLVED: To reduce the oscillation of a building to a prescribed direction without installing attenuation means at a framework face of a column beam framework which is arranged in the prescribed direction of the building.SOLUTION: A vibration control structure of a building has: the building having a plurality of columns which are arranged along a first direction and a second direction which intersects with the first direction; a first beam which is arranged in the first direction, and bridged between the columns; a second beam which is arranged in the second direction, and bridged between the columns; a plurality of first framework faces which are formed of the first beam and the columns in a vertical direction; and a plurality of second framework faces which are formed of the second beam and the columns in the vertical direction; a low-rigidity framework face which is formed in the second direction while the columns are not installed in any story other than the uppermost story of the building; and attenuation means which is arranged at the low-rigidity framework face or the second framework face of an upper story of the low-rigidity framework face, and absorbs the vertical vibration of the second beam which is arranged at an upper part of the low-rigidity framework face.SELECTED DRAWING: Figure 1 【課題】建物の所定方向に配置された柱梁架構の架構面に減衰手段を設けずに、この所定方向に対する建物の揺れを低減する。【解決手段】第１方向と前記第１方向と交差する第２方向に沿って複数設けられた柱、前記第１方向に配置され前記柱間に架設された第１梁、前記第２方向に配置され前記柱間に架設された第２梁、前記第１梁と前記柱により上下方向に複数構成された第１架構面、及び前記第２梁と前記柱により上下方向に複数構成された第２架構面を有する建物と、前記建物の最上階以外の何れかの階に前記柱を設けないことにより前記第２方向に構成された低剛性架構面と、前記低剛性架構面又は前記低剛性架構面の上階の前記第２架構面に設けられ、前記低剛性架構面の上部に配置された前記第２梁の上下振動を吸収する減衰手段と、を有する建物の制振構造。【選択図】図１
