The report is a sequel of the last announcement and it treated also the numerical calculation of the buckling load of the thin deep beam. The cross sections of the beam have two portions of variable and constant ones, and are symmetrical to the middle of the span. The variable cross sections change gradually according to the next law : [numerical formula] B and C are the bending and torsional rigidities of the cross sections, and a, b are constants, and m, n are real numbers greater than unity. By using the conditions at the beam ends and the connecting sections of constant and variable portion, we can find the buckling moment of such a beam. The buckling moment is taken as following formula : [numerical formula] Where B_0,C_0 are the rigidities of fundamental cross sections. The ccefficient μ depends upon the shape of beam.
