# Export : OpenSees

The model data can be exported to an OpenSees (opens new window) TCL file.

# Export

The user can select:

Which analysis stage should be exported.
Which case loads ere exported in.
To export bars as OpenSees trusses or corotational trusses.
To export steel and concrete beams (as separate choices) as OpenSees elastic, nonlinear or displacement beam columns.
To export section properties or section shapes.

The following restrictions apply:

Spacer elements not exported.
Spring elements in non-global directions are approximate. The spring is assumed to act in the closest global direction.
In spring elements non-axial/torsional effects are ignored.
No distinction is made between applied displacements and settlements.
The axis is ignored for applied displacements.
Beam loads in user axes are transferred in global axes.
Face load axes are ignored and pressure assumed normal to surface.
Edge loads on 2D elements are ignored.
Prestress and in-plane loads are converted to equivalent thermal loads.
