Axially loaded simply supported channel, free to warp

0015 - Nonlinear torsion

Test of the Wagner strain term with standard 6-DOF frame elements.

0017 - Axial-torsional buckling under axial force.

A simply supported column with symmetric section (+ and I) buckles in torsion under the action of an axial load.

0027 - Rigid Offsets

This example tests the effect of rigid joint offsets in a diamond-shaped frame. The analytical solution is known, and the test is used to verify the correct treatment of offset geometry in a 3D frame element.

0100 - Plastic hinging

0100 - Plastic hinging

Plastic hinging in a fix-fix girder under a point load is simulated using J2 plasticity.

021 - Concrete columns with shear

1001 - Finite Rotations

1001 - Finite Rotations

This problem highlights the exceptional accuracy of the ExactFrame formulation for simulating large deformations

1002 - Cantilever with transverse loading (Postbuckling)

1002 - Cantilever with transverse loading (Postbuckling)

In this case the cantilever beam is subjected only to a transverse force of $\boldsymbol{F} = 10 \, \mathbf{E}_2$ in a single step.
