UNDERSTRUCTURE OF BRIDGE
PROBLEM TO BE SOLVED: To maintain a function of a friction damper without degrading economical efficiency when building the friction damper in a vibration control mechanism.SOLUTION: In an understructure 1 of a bridge according to the present invention, posts 3 are respectively raised so as to mutually face footings 2, 2, and a beam 4 is bridged on a top part of the pair of posts 3, 3, thus, the posts 3, 3 and the beam 4 constitute a rahmen bridge frame 5 as a post beam bridge frame. At respective inner corner parts which are inner spaces surrounded with the pair of posts 3, 3 and the beam 4 for interaction of the post 3 and the beam 4, a friction damper 7 is diagonally arranged for bracing support, and each end of the friction damper is jointed to the post 3 and the beam 4 through a plastic hinge mechanism 6.SELECTED DRAWING: Figure 1
【課題】摩擦ダンパーを制振機構に組み込む際、経済性を損なうことなく、摩擦ダンパーの機能を維持する。【解決手段】本発明に係る橋梁の下部構造１は、フーチング２，２に互いに対向するように柱３をそれぞれ立設するとともに、これら一対の柱３，３の頂部に梁４を架け渡して構成してあり、柱３，３及び梁４は、柱梁架構としてのラーメン架構５を構成する。一対の柱３，３及び梁４で囲まれた内側空間であって柱３と梁４とが取り合う各入隅部には、摩擦ダンパー７を頬杖状に斜め配置してあるとともに、該摩擦ダンパーの各端を塑性ヒンジ機構６を介して柱３と梁４にそれぞれ接合してある。【選択図】 図１
