HIGH-RISE BUILDING AND PRECAST PRE-STRESSED CONCRETE COLUMN
To achieve reduction of the construction period of a high-rise building and improvement of the durability of tendons.SOLUTION: A high-rise building 10 comprises a plurality of precast pre-stressed concrete columns 12 each provided on respective floors and a plurality of vibration control devices 30 restraining the vibration of the building. Precast pre-stressed concrete columns 12 are constituted including concrete column bodies 16 and tendons 18. Column main reinforcements 1602 and hoop reinforcements 1604 are embedded in the concrete column bodies 16 and a plurality of tendon insertion holes 1606 are penetrated and formed into the longer direction. The tendons 18 are inserted into respective tendon insertion holes 1606 and disposed at the concrete column bodies 16 in unbonded state in the vertical direction. The vibration control devices 30 restrain the vibration of the high-rise building 10 such that the deformation of tendon 18 due to the vibration of the high-rise building 10 is settled within the elastic range of tendon 18.SELECTED DRAWING: Figure 3
【課題】高層建物の工期の短縮化を図り、緊張材の耐久性の向上を図ること。【解決手段】高層建物１０は、各階毎に設けられた複数のプレキャストプレストレストコンクリート柱１２と、建物の揺れを抑制する複数の制振装置３０とを備えている。プレキャストプレストレストコンクリート柱１２は、コンクリート柱体１６と緊張材１８とを含んで構成されている。コンクリート柱体１６は、柱主筋１６０２とフープ筋１６０４が埋設されると共に複数の緊張材挿通孔１６０６がその長手方向に貫通形成されている。緊張材１８は、各緊張材挿通孔１６０６に挿通され、コンクリート柱体１６に鉛直方向にアンボンド状態で配置されている。制振装置３０は、高層建物１０の揺れによる緊張材１８の変形が緊張材１８の弾性範囲内に収まるように高層建物１０の揺れを抑制する。【選択図】図３
