Сoordinate functions quadratic approximation in V.I. Slivker's semi-shear stability theory

Variational formulation of stability problems for thin-walled beams is presented. Geometrical stiffness matrix is derived from the stability functional. Shear deformation is taken into account by using V.I.Slivker’s semi-shear theory of thin-walled bars. Quadratic Hermite polynomials were considered...
