CONNECTION LOAD BEARING CAPACITY EVALUATION METHOD FOR COLUMN-BEAM CONNECTION STRUCTURE, DESIGN METHOD FOR COLUMN-BEAM CONNECTION STRUCTURE, AND COLUMN-BEAM CONNECTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a connection load bearing capacity evaluation method for a column-beam connection structure that enables a column flange plate thickness and a web plate thickness to be reduced further, taking into consideration appropriately a load burdening effect of concrete.SOLUTION: A connection load bearing capacity evaluation method is for a non-diaphragm-type column-beam connection structure with a steel framed reinforced concrete column 11, a steel beam 21, and a connection 31 where the beam is connected to the column. The column 11 includes a steel column 12 having a web 14 and a flange 13. The beam 21 includes a web 24 and a flange 23, and is connected to the flange 13 of the steel column 12 at the connection 31. An evaluation is made on the connection 31, taking into consideration bearing capacity of concrete on an inner side D1 in a thickness direction of the flange of the steel column to withstand bearing fracture, in which the flange of the steel column is deformed toward the inner side in the thickness direction of the flange, when force generated by the flange on a compression side of the beam on the flange of the steel column is exerted to press-in the flange of the steel column in a thickness direction D, in addition to bearing capacity of the steel column.SELECTED DRAWING: Figure 3
【課題】コンクリートの耐力負担効果を適切に考慮して、柱のフランジの板厚及びウェブの板厚をより薄くすることができる柱梁接合構造の接合部耐力評価方法を提供する。【解決手段】鉄骨鉄筋コンクリート造の柱１１と、鉄骨造の梁２１と、柱に梁が接合された接合部３１、を備えるノンダイアフラム形式の柱梁接合構造の接合部耐力評価方法であって、柱１１は、ウェブ１４とフランジ１３とを有する柱鉄骨１２を備え、梁２１は、ウェブ２４とフランジ２３とを有し、接合部３１において柱鉄骨１２のフランジ１３に接合されていて、接合部３１について、柱鉄骨の耐力に、梁の圧縮側のフランジが柱鉄骨のフランジを柱鉄骨のフランジの厚さ方向Ｄに押し込む力に対して、柱鉄骨のフランジが厚さ方向の内側Ｄ１に変形するときの柱鉄骨のフランジの厚さ方向の内側のコンクリートの支圧破壊に対する耐力を加えて評価する。【選択図】図３
