• This paper treats various eccentric axial compression experiment of carbon steel cylindrical pipes with a circular hole. The edge condition of the pipe column supported with spherical seats. The length of pipes exisit in a short column range. The measurement reveals that collapse of the pipes occurred as the local buckling of circular hole. It was found that the buckling load decreased as the open ratio dE0124/D and eccentric ratio ξ increased. In consideration of experimental result, an empirical formula for calculating eccentric axial compressive buckling load "P_<che>" is presented as follows; P_<che>/P_<cr> = (P_<crh>/P_<cr>)・(P_<cre>/P_<cr>) where P_<cr> : axial compressive buckling load of pipes without a circular hole. P_<crh> : axial compressive buckling load of pipes with a circular hole. P_<cre> : eccentric axial compressive buckling load of the pipes without a circular hole.
