On Clamped Girders Supports of Thin-Walled Structures Under Bending

Clamped supports of thin-walled structures under bending as ship structures are considered. The beam clamped support is defined as the section with zero rotation of the beam cross-section as rigid contour. It is the case of the cross-section in the structure plane of symmetry with loads symmetrical with respect to the plane of symmetry. By the structure symmetry it is assumed the geometrical symmetry (the beams lengths and the cross-section geometrical properties), the boundary conditions and the material elastic constants. The rotation of the cross-section as rigid contour can also be prevented in some special cases of the structure asymmetry. Analyses and verification of such cases are performed on examples of tankers and container ships frame structures. The theory of bending of thin-walled beams with influence of shear (TBTS) and the finite element method (FEM) are applied.
