3. Modeling A#
3.1. Characteristics of modeling#
A DIS_TR_L element with 2 nodes of zero size (idem [§1.1]).
An N2 node: we block everything.
An N3 node: we impose \(\mathrm{Fy}\) in \(\mathrm{500 }N\) steps with the time map:
\(t\) |

\(F(t)\) |
3.2. Characteristics of the mesh#
1 SEG2.
2 knots.

3.4. notes#
General:
Behavior ARME can also be used in Nonlinear Dynamic Analysis but is not tested.
