DESIGN METHOD OF STEEL PIPE JOINT, STEEL PIPE JOINT, AND STRUCTURE
To more effectively suppress deformation of a joint structure by evaluating three-dimensional deformation.SOLUTION: A steel pipe joint includes: an outer fitting end which is provided at one end of a first steel pipe and in which a plurality of outer fitting steps having a plurality of crests arranged in a pipe axial direction and a plurality of outer fitting grooves extending in the pipe axial direction are alternately arranged in a pipe circumference direction, and an inner fitting end which is provided at one end of a second steel pipe and in which a plurality of inner fitting steps having a plurality of crests and a plurality of inner fitting grooves are alternately arranged in the pipe circumference direction. The inner fitting end fits inside the outer fitting end to connect the first steel pipe and the second steel pipe. At least one of the outer fitting end or the inner fitting end is designed so that formula (i) is satisfied for a base end pipe thickness tp, a material specification ratio η of the first steel pipe and the second steel pipe, a tip crest height hg, a tip valley pipe thickness t1, a base valley pipe thickness tn, a step length L in the pipe axial direction, a groove length B in the pipe circumference direction, and a stress effective width coefficient β.SELECTED DRAWING: Figure 10
【課題】３次元的な変形を評価することによってより効果的に継手構造の変形を抑制する。【解決手段】第１鋼管の一端に設けられ、管軸方向に配列された複数の山部を有する複数の外嵌段部と管軸方向に延びる複数の外嵌溝部とが管周方向に交互に配列された外嵌端部、および第２鋼管の一端に設けられ、複数の山部を有する複数の内嵌段部と複数の内嵌溝部とが管周方向に交互に配列された内嵌端部を含み、内嵌端部が外嵌端部の内側に嵌合することによって第１鋼管と第２鋼管とを連結する鋼管継手において、外嵌端部または内嵌端部の少なくともいずれかを、基端部管厚ｔｐ、第１鋼管および第２鋼管の材料規格比η、先端山部高さｈｇ、先端谷部管厚ｔ１、根元谷部管厚ｔｎ、管軸方向の段部長さＬ、管周方向の溝部長さＢ、および応力有効幅係数βについて式（ｉ）を満たすように設計する。TIFF2024141787000013.tif23165【選択図】図１０
