I will show the buckling analysis of a beam by nonlinear beam element of total lagrangian formulation. The beam element has not only the geometric stiffness of rotation but also the geometric stiffness of large strain. As the results of the analysis, it will be shown that the buckling loads of the beam element are less than the theoretical buckling loads.
