BEAM JOINT STRUCTURE AND CALCULATION METHOD OF ROTATIONAL RIGIDITY OF BEAM JOINT STRUCTURE
To provide a beam joint structure suppressing damage on an end part of a beam even when the end part of the beam is negatively bent.SOLUTION: A beam joint structure 2 is provided with: a supporting member 21 provided with a shear plate 25; a beam 31 having a web 32 and a flange 33, being arranged to extend from the shear plate; a bolt 41 connecting an end part of the web of the beam and the shear plate using friction force; a transmission member 51 arranged on the flange of the beam and transferring a bending moment on the beam to the supporting member. Rotational rigidity at the end part of the beam in the beam joint structure is equal to or less than an upper limit of the rotational rigidity at the end part of the beam in a first reference structure when the first reference structure is defined as a beam joint structure where an absolute value of the bent moment generated at the end part in an axial direction of beam material is equal to an absolute value of the bent moment generated at a center in the axial direction of the beam material.SELECTED DRAWING: Figure 2
【課題】梁の端部が負曲げされても梁の端部が損傷するのを抑制した梁接合構造を提供する。【解決手段】シアプレート２５が設けられた支持部材２１と；ウェブ３２とフランジ３３とを有し、シアプレートから延びるように配置された梁３１と；梁のウェブの端部とシアプレートとを摩擦接合するボルト４１と；梁のフランジに設けられ、梁に作用する曲げモーメントを支持部材に伝達する伝達部材５１と；を備える梁接合構造２において、梁の材軸方向の端に発生する曲げモーメントの絶対値と梁の材軸方向の中央に発生する曲げモーメントの絶対値とが同等になる梁接合構造を第１基準構造としたときに、梁接合構造の梁の端の回転剛性は、第１基準構造の梁の端の回転剛性である回転剛性上限値以下である。【選択図】図２
