Verification of lira-sapr calculation of i-beams with two symmetry axes for general stability in transverse bending in the plane with maximum stiffness

Blog Article

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) made goods jarin dresser LIRA-SAD.Calculations for various loads are given.Numerical calculation results in PC LIRA-SAP are compared with calculation by 006719f 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.
