The paper considers verification of calculation of split I-beams with two symmetry axes on the general Eulerian stability at transverse bending in the plane of maximum stiffness in the software package (PC) LIRA-SAD. Calculations for various loads are given. Numerical calculation results in PC LIRA-SAP are compared with calculation by analytical formulas of S.P. Timoshenko and V.Z. Vlasov. Conclusions about calculation accuracy in PC LIRA-SAD in comparison with analytical formulas analysis are made.
