概要 For the examination of building collapse, it is required to analyze the building performance using the pertinent analytical model for the columns. The residual axial load capacity of the column after shear compression failure in the bending hinge zone is different from the capacity of the columns after shear tension failure. This paper investigates the analytical model for the column experienced failure in the bending hinge zone based on the M-N surface contraction. The reduction rate was obtained as a function of the maximum deformation, shear margin ratio, strength of longitudinal and transverse reinforcement, using the regression analysis of experimental results. The tested results are explained by this formula with good agreement.
