WIND RESISTANT DEVICE
To provide a wind resistant device capable of exhibiting excellent wind-resistant performance together with a base isolation device set in a base isolation layer, while reducing the number of the wind resistant devices set in the base isolation layer to the utmost.SOLUTION: A wind resistant device 90 is installed between a lower structure 10 and an upper structure 20 both forming a base isolation layer 102 of a base-isolated building 100, together with a base isolation device 50 formed of a base isolation support 30 having an attenuation damper 40. In the wind resistant device 90 having a raised-up body 60, a rising up body 70 rising up in relation to the raised-up body 60 and a friction stopper 80, the rising up body 70 is an upper bearing plate 71 having a first recess 72 on an undersurface, the raised-up body 60 has a spherical body 63 with one part thereof housed in the first recess 72 and a lower bearing plate 61 having a second recess 62 housing the other part of the spherical body 63, on an upper face. A plane size of the second recess 62 is larger than that of the spherical body 63.SELECTED DRAWING: Figure 4
【課題】免震層において設置される耐風装置の数を可及的に低減しながら、免震層に存在する免震装置とともに優れた耐風性能を発揮することのできる耐風装置を提供すること。【解決手段】免震建物１００の免震層１０２を構成する下部構造体１０と上部構造体２０の間において、減衰ダンパー４０を有する免震支承３０により形成される免震装置５０とともに配設される耐風装置９０であって、被せり上がり体６０と、被せり上がり体６０に対してせり上がるせり上がり体７０と、摩擦ストッパー８０とを備える耐風装置９０において、せり上がり体７０は下面に第１窪み７２を備えている上方支圧板７１であり、被せり上がり体６０は、第１窪み７２に一部が収容される球体６３と、球体６３の他部が収容される第２窪み６２を上面に備えている下方支圧板６１と、を有し、第２窪み６２の平面寸法が球体６３の平面寸法よりも大きい。【選択図】図４
