| Abstract: | The theme investigated in this paper is analyzed on the basis of the section properties of Ⅰ—Beams. The formulas and the method for the solution to the shear center axis are given, and the calculating crrors of indiserimirtately applying the uniform formulas obtained. Thus, the theoretical base and practical formulas for such problems about nonuniform Ⅰ—Beams as torsion, flexion in two direstions, torsionsal—flexursal buckling etc are presented. |
