## Lateral Buckling of a Beam in Pure Bending

VE 0095

30 April 2019

A simply supported beam is loaded by means of pure bending. Determine the critical load and corresponding load factor due to lateral buckling.

## Eight-Member Symmetric Shallow Truss Snap-Through

VE 0201

8 October 2018

A symmetrical shallow structure is made of eight equal truss members, which are embedded into hinge supports. The structure is loaded by the concentrated force and alternatively by the imposed nodal deformation over the critical limit point when the snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection considering large deformation analysis. Evaluate the load factor at given deflections.

## Four-Member Truss Snap-Through

VE 0200

5 October 2018

A structure is made of four truss members, which are embedded into hinge supports. The structure is loaded by a concentrated force and alternatively by imposed nodal deformation over the critical limit point, when snap-through occurs. Imposed nodal deformation is used in RFEM 5 and RSTAB 8 to obtain full equilibrium path of the snap-through. The self-weight is neglected in this example. Determine the relationship between the actual loading force and the deflection considering large deformation analysis. Evaluate the load factor at given deflections.

## Buckling of a Circular Ring

VE 0094

10 July 2018

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

VE 0093

10 July 2018

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.

## Asymmetric Snap-Through

VE 0046

8 January 2016

A structure is made of two trusses of unequal length, which are embedded into the hinge supports. The structure is loaded by the concentrated force.

## Snap-Through

VE 0045

23 December 2015

A structure is made of two trusses, which are embedded into the hinge supports. The structure is loaded by the concentrated force.
