WALL SURFACE STRUCTURE OF BUILDING, WIND SHAKE RESTRAINING MECHANISM OF BUILDING, AND WIND SHAKE RESTRAINING METHOD OF BUILDING
To provide a wind shake restraining technology suitable for a building such as a high-rise building.SOLUTION: A building 2 is a vertically elongated rectangular parallelepiped-shaped building such as a high-rise building, and uneven structures 1 as wall structures are provided on wall surfaces 20a, 20b on both right and left sides for the advancing direction (wind direction N) of wind blowing to the building 2. The uneven structure 1 is constituted by regularly arranging a plurality of projection parts 10 projecting from a wall surface 20 on the wall surface 20. For the wind direction N, the formation of Karman vortices generated in the periphery of the building 2 is promoted by the uneven structure 1 provided on the wall surfaces 20a, 20b on both right and left sides of the building 2, and the period of the wind pressure fluctuation V on both right and left sides of the building 2 is shortened for the wind direction N, thereby making the period of the wind pressure fluctuation V away from the natural frequency of the building 2 and suppressing the generation of the rocking phenomenon.SELECTED DRAWING: Figure 1
【課題】高層ビル等の建築物に好適な風揺れ抑制技術を提供する。【解決手段】建築物２は、高層ビル等の垂直方向に細長い直方体形状の建築物であり、この建築物２に吹き付ける風の進行方向（風向Ｎ）に対して左右両側の壁面２０ｂ、２０ｃに、壁面構造としての凹凸構造１が設けられている。凹凸構造１は、壁面２０から突出する複数の突起部１０を壁面２０に規則的に配置することにより構成される。風向Ｎに対して建築物２の左右両側の壁面２０ｂ、２０ｃに設けた凹凸構造１により、建築物２の周辺に発生するカルマン渦の形成を促進して、風向Ｎに対して建築物２の左右両側における風圧変動Ｖの周期を短くし、これにより、この風圧変動Ｖの周期を建築物２の固有振動数から遠ざけて、ロッキング現象の発生を抑制することができる。【選択図】図１
