To export a model to STAAD, see the following limitations and instructions.
The scope of the STAAD Export is constrained by the limitations of the STAAD Text File (.std) format.
Elastic extensions cannot be defined in STAAD. Therefore, additional 1D elements are created to preserve model connectivity.
The exported file will not group elements in any way. 1D elements will not be grouped as members (or columns, beams, etc). In addition, there will not be any grouping of faceted elements from a curved member. 2D elements will not be grouped into panels.
Section data is exported as analysis properties only. This means that no attempt is made to reference STAAD library sections.
Material data is exported as analysis properties only. This means that no attempt is made to reference STAAD library materials.
Objects such as Shear Only Walls have no equivalent native object in STAAD and some of the internal data such as panel geometry and spring properties end up lost during conversion.
Create the model as usual.
On the BIM Integration tab, click STAAD Export.
The Save As dialog opens.
If necessary, change the name and location of the file.
