ASEISMIC REINFORCEMENT STRUCTURE FOR BUILDING
PROBLEM TO BE SOLVED: To avoid that earthquake force generated in an intermediate passing floor is added to a brace while avoiding that reinforcement effect by the brace is directly provided on intermediate passing floor by adopting a mechanism where the brace and a special configured anti-buckling part are used so as to directly transmit earthquake force generated in an upper layer floor to a lower layer floor.SOLUTION: The following means is applied to an aseismic reinforcement structure. An upper joint structure 2 receiving horizontal earthquake force in an upper layer floor is arranged. A lower joint structure 3 is arranged on a lower layer floor which is designed to have intermediate passing floors from the upper layer floor. The upper joint structure 2 and the lower joint structure 3 are connected with right and left braces 4. Anti-buckling parts 5, on which the braces 4 may slide in axis direction and rotating direction, are arranged on intersection points of the intermediate passing floor and the right and left braces 4, and the braces 4 are attached thereto. The braces 4 directly transmit compressing and pulling forces due to horizontal earthquake force to the lower joint structure 3, in which the braces 4 do not transmit horizontal earthquake force received from the upper joint structure 2 to the intermediate passing floors and do not receive horizontal earthquake force generated in the intermediate passing floors.SELECTED DRAWING: Figure 1
【課題】ブレースと特殊構成の座屈止を用いて、上層階に生ずる地震力を、直接下層階に伝達する機構を採用し、途中通過階に生ずる地震力がブレースに加算されることを回避すると同時に、ブレースの補強効果が直接的に途中通過階に及ぶことを回避する。【解決手段】耐震補強構造に、次の手段を採用する。上層階の地震水平力を受ける上部接合構造体２を設ける。上層階から途中通過階を設定した下層階に下部接合構造体３を設ける。上部接合構造体２と下部接合構造体３とを左右のブレース４で連結する。途中通過階と左右のブレース４との交点に、ブレース４が材軸方向及び回転方向に摺動可能な座屈止５を設置し、ブレース４を装着する。ブレース４が、上部接合構造体２より受けた地震水平力を、途中通過階に伝達することなく、且つ、ブレース４が途中通過階に生じる地震水平力を受けることなく、地震水平力による圧縮及び引張の力を下部接合構造体３に直接伝達する。【選択図】図１
