抄録

In the present study, the authors reexamined experimental data on stress sharing of constituent elements of SRC interior beam-column joints to clarify the stress-transfer mechanism of SRC interior beam-column joints. The following conclusions were obtained. The shear strengths of transverse steel flanges depend on the distance and the beam column depth ratio of the transverse flanges. The shear strengths of RC differ in the confined effect on concrete by the differences in steel column cross-sectional shape. It was clarified that concrete stress in the ultimate shear strength of a SRC beam-column joint was transmitted by the strut on the diagonal line of the beam-column joint. A convenient method was proposed for obtaining the strut width. In addition, regarding the effective width of beam-column joints, each stress in the three zones where stress transmission seemed to differ was clarified; an equation of the effective width of beam-column joints was proposed. Adequate shear strength estimation for SRC beam-column joints was also proposed. As a result, the correspondence of calculated and experimental values was drastically improved.
