Joint hinging failure and succeeding axial failure of a R/C corner column-beam joint were investigated by static tests with three-dimensional beam-column subassemblages under varying axial and bi-lateral loads, where the axial compression stress ratio ranged from 0 to 0.13. Corner joints suffering joint-hinging failure were not able to sustain column axial load at a story drift angle of 3% to 4%, resulted in joint axial failure. This was caused by crushing of joint core concrete, pull-out of a 135-degree hook of joint lateral hoops due to dilation of joint concrete, and buckling of column longitudinal bars in the joint region.
