On the basis of analyzing all the forces on the self-supported uniform high column, the superposition method in mechanics of materials and a MATLAB program were used to calculate the additional moments on arbitrary section for the high column under both weight and distributed wind pressure. A formulation of additional maximum moment is deduced. The results show that the effect of weight to wind moments of the heavy weight high columns cannot be ignored.
