VIBRATION CONTROL STRUCTURE USING VERTICAL PRESTRESS
PROBLEM TO BE SOLVED: To provide a vibration control building structure capable of acting against a shake caused with horizontal force and drawing force of a column base part by a vibration control function using vertical prestress imparted to a column.SOLUTION: A prestress vibration control building structure 1, as a high-rise or very high-rise building structure is constructed with pluralities of columns 10 and beams 11. A tendon 30 for imparting prestress at least to a cross section of an outer peripheral column 10a of the building is arranged to the overall length of the column, and the tendon 30 has its upper end tensed and fixed to the top floor. An extension tendon 31 is coupled to a lower end thereof through a coupling part 6 and extended in the foundation G to a necessary depth to be fixed, the tendon 31 is formed of an unbonded structure part 31a and a bonded structure part 31a, and restoring force is increased by absorbing drawing force through extension of the unbonded structure part 31a of the extension tendon 31 and hardly causing tension acting on the tendon 30 to increase above initial tension.SELECTED DRAWING: Figure 1
【課題】柱に付与された鉛直プレストレストによる制震機能によって水平力による揺れや柱脚部の引抜力に対抗することができる制震建造物を提供する。【解決手段】複数の柱１０と梁１１とで構築される高層または超高層建造物１であって、少なくとも該建造物の外周柱１０ａの断面にプレストレスを付与する緊張材３０が柱全長に亘って配置され、該緊張材３０の上端は最上階に緊張定着され、下端には延長緊張材３１が連結部６を介して連結されて地盤Ｇの所要深さまで延長されて定着されており、該延長緊張材３１がアンボンド構造部３１ａとボンド構造部３１ｂとで形成され、引抜き力を延長緊張材３１のアンボンド構造部３１ａの伸びによって吸収することによって緊張材３０には作用する張力が初期緊張力以上にはほとんど増加しないようにして復元力を高めたプレストレス制震建造物１である。【選択図】図１
