Is there any direct way to define a pinned end (aka hinge, moment release) on a beam element? It seems possible to do this using a zero-length element with "zero" stiffness in the moment direction and "infinite" stiffness in the axial and shear directions, but this approach may cause numerical problems.
Any better methods?

1. Define two nodes at the same coordinates.
2. Use equalDOF command to constrain translational degrees of freedom
3. Connect the column to $nodeI, and the beam to $nodeJ
2. Use equalDOF command to constrain translational degrees of freedom
Code: Select all
equalDOF $nodeI $nodeJ 1 2
