EARTHQUAKE STRENGTHENING DEVICE FOR GATEPOST
To provide an earthquake strengthening device configured to improve earthquake performance of dam gateposts in a direction of an axis of a dam, of which a structure is to install an earthquake-proof brace and surrounding frames transmitting to a damper a horizontal displacement difference between two points, A and B, with different heights of the gateposts upon an earthquake, in loss as small as possible, or install then from surfaces of the gateposts.SOLUTION: An earthquake strengthening device for gateposts arranged between gateposts 1 installed in a dam 16 in accordance with the present invention is configured: to attach a truss frame 2 made of connection members connected in a truss configuration in a frame body formed with an upper chord member 5 and a lower chord member 4, and upper parts of posts connecting the upper chord member 5 and the lower chord member 4 by stretching it between the posts on an upper part of posts 7 connected to the gateposts 1; and to connect earthquake-proof braces 3 between a lower part of the truss frame 2 and post legs.SELECTED DRAWING: Figure 1
【課題】本発明はダム門柱のダム軸方向の耐震性能を向上する構造として、門柱の高さの異なるＡ、Ｂ２点間の地震時水平変位差を極力小さなロスでダンパーに伝達させる制震ブレース及び周辺架構を門柱間に設置、または門柱側面から設置する構造を提供する。【解決手段】本発明は、ダム１６内に設けられた門柱１の間に設けられる門柱耐震補強装置であり、門柱１に接続した柱７の上部に、上弦材５と下弦材４及び上弦材５と下弦材４を繋ぐ柱上部で形成された枠体内にトラス状に連結した連結部材で構成されたトラス架構２を柱間に掛け渡して取り付け、該トラス架構２の下部と柱脚部間に制震ブレース３を連結して門柱耐震補強装置を構成してなることを特徴とする。【選択図】 図１
