鉄筋コンクリートはり柱接合部における付着すべり

Abstract

Parametric analyses were carried out. Variable was the height of the column. Design criteria was proposed to prevent the bond failure of beam bars in the joint. The length of the yield penetration region in the joint was evaluated by the following equation, [numerical formula] where μ was the ductility factor, ε_y was the yield strain of beam bar, ε_<SH> was the strain at the onset of strain hardening, and l' was the shear span length of the beam. The effects of the pull-out from the joint upon the bond failure of column bars in short columns were also studied. Considering these effects, design criteria to prevent the failure was proposed.
