In this work the buckling of a column with bent butts is investigated. It is established that critical force at which there is a loss of buckling of the rectilinear form of balance, essentially depends on radius of curvature of butt surfaces. The bigger curvature radius, the more intensive is critical force. The parametrical equations of the bent axis of a column for any values of longitudinal force are received. The critical size of loading at which the column ceases to lean against the butt surfaces is found.
