Description
上記面材の裏面側には、上記軸材に対応した辺に沿って細長い受材が設けられていると共に、該受材には、上記制振部材が該受材の長さ方向に沿って複数設けられており、
上記複数の制震部材のそれぞれは、軸材取付部が上記軸材の上記面材に直交する面に取り付けられていると共に、面材取付部が上記受材を介して上記面材の裏面側に取り付けられていることを特徴とする。
左右に間隔をおいて並行に延びるように設けられた一対の第1軸材と、上下に間隔をおいて並行に延びるように設けられた一対の第2軸材と、を有し、該一対の第1軸材のそれぞれが該一対の第2軸材間を連結するように立設されて構成された枠状の躯体を備え、
上記複数の制震部材が取り付けられた上記軸材は、上記躯体の上記一対の第1軸材及び上記一対の第2軸材のうちに含まれており、
上記面材は、上記躯体を覆うように設けられていると共に、周縁に沿って、間隔をおいて、剛性を有する材料で形成された固定具が複数打ち付けられ、それによって上記一対の第1軸材及び上記一対の第2軸材のそれぞれに固定されていることを特徴とする。
上記制震部材は、主鎖にC−C結合を有するポリマーからなる基材ゴムに、該基材ゴム100質量部に対して100〜150質量部のシリカと、該シリカの10〜30質量%のシラン化合物と、が添加されて架橋されたゴム組成物で形成された粘弾性ダンパーを有することを特徴とする。
図1〜3は、本発明の実施形態1に係る建物の制震構造10を示す。
Heq=ΔW/2πW
W:剪断変形の弾性エネルギー(N・mm)(図6(b)中の斜線部分の面積)
ΔW:剪断変形により吸収するエネルギーの合計(N・mm)(図6(b)中の楕円部分の面積)
Geq=Keq/(S/D)=F/UBE/(S/D)
F:最大変位を与えるときの荷重(N)
UBE:最大変位(mm)
S/D:試験サンプルの形状係数(サンプル剪断面積/サンプル剪断隙間)
また、一般的な粘弾性体は、振動周波数の増加に伴ってGeq(N/mm2)が著しく大きくなる。例えば、20℃では、振動周波数0.1Hzのときと2.0HzのときとではGeqの値が2〜3倍となる。交通振動の卓越周波数は通常4〜7Hzに分布し、地震動は0.1〜20Hz程度に分布するので、制震材用の粘弾性体としては、より入力周波数分布領域が広範囲に及ぶ地震動に対して、剛性や減衰性能の点で比較的安定した性質を備えていることが好ましい。
Geq(t=−10℃)/Geq(t=20℃)≦2.2
であり、且つ、高温側は40℃のときのGeq(t=40℃)と20℃のときのGeq(t=20℃)との比
Geq(t=40℃)/Geq(t=20℃)≧0.6
であることが好ましい。
