Verification Examples

Euler Buckling

A strut with circular cross-section is supported according to four basic cases of Euler buckling and it is subjected to pressure force. Determine the critical load.

Buckling of a Circular Ring

A thin circular ring of rectangular cross-section is exposed to an external pressure. Determine the critical load and corresponding load factor for in-plane buckling.

Buckling of Beam with Various Cross-Sections

A column is composed of a concrete part - rectangle 100/200 and of a steel part - profile I 200. It is subjected to pressure force. Determine the critical load and corresponding load factor. The theoretical solution is based on the buckling of a simple beam. In this case two regions have to be taken into account due to different moment of inertia and material properties.

Stability of a Beam with Various Support Stiffness

An axially loaded steel beam with a square cross-section is pinned at one end and spring supported at the other. Two cases with different spring stiffness are considered. Neglecting its self-weight, determine the critical load scaling factors by the linear stability analysis.

Stability of a Beam Subjected to the Combined Loading

A steel beam with a square cross-section is loaded with an axial force and a distributed loading. Calculation of the maximum bending deflection and the critical load factor according second order analysis.
