The paper considers female galaxy skin 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 hae43ec in comparison with analytical formulas analysis are made.
