概要 Shear failure of columns may lead to collapse for existence buildings. After a severe earthquake, some buildings collapsed by loss of axial capacity of the columns, however, some buildings have stayed even many columns were fractured by shear. For the examination of building collapse, it is required to investigate the axial load capacity of the columns after shear failure and to analyze the building performance using the pertinent analytical model for the columns. This paper investigates the analytical model for the collapse analysis of a building based on Yoshimura’s concept of the failure surface contraction. The reduction rate was obtained as a function of the maximum deformation, shear margin ratio, and so on, using the regression analysis of experimental results. The tested results are explained by this formula with good agreement.
