Tips and limitations for exporting from Tekla Structures

General recommendations

  • Please note that in IDEA StatiCa Connection are members only beam entities on which loads will be applied. All other beams are defined in a different way. This rule goes in hand with the three-step import procedure. In the imports second step, the members (on which loads will be applied) have to be selected. In the third step all other connection entities have to be selected – plates, bolts, welds and most importantly beams on which loads will not be applied (usually stubs, stiffening members, etc).
  • Always check, there are no gaps between plates and members in your Tekla Structures model before starting the import procedure.
  • Always check the welds in your Tekla structures model before starting the import procedure.


IDEA StatiCa Connection can import a huge variety of the cross-sections from the Tekla Structures. The import procedure supports these types of the cross-sections:

Cross-section type Tekla parametric input

Tekla library input

U - X
L   X
Circular hollow X X
Rectangular hollow X X
Rectangular plate X -
Cold formed C X X

Parametric input is user-defined dimensions of required cross-section type. Library input is cross-section selected from Tekla library.

During the import process, the imported cross-section is matched with the appropriate cross-section in IDEA StatiCa Connection databases and the most similar cross-section is chosen. If there isn’t a match, the conversion table is offered, and the user must choose cross-section from the IDEA StatiCa databases.

Welded and composite cross-sections are not supported.

The user should pay attention to the library cross-section parameters because library in Tekla Structures doesn’t contain information about roundings of hot-rolled sections. IDEA StatiCa Connection defines missing values by its own library tables.

Holes-openings and notches

  • Openings in plates are supported and will be imported. Openings in members are not supported.

A workaround is to import the whole joint and manually add Opening as a manufacturing operation in the IDEA StatiCa Connection.

  • Notches in plates and members are supported and will be imported but there is a requirement for a successful import. The size of the cross section which is cut must be the same as the size of the cross-section for the cut.

Please note that the general polygon as a cutting shape is not supported. Welds on notched elements are not supported either.

If the welds are needed it must be defined in the IDEA StatiCa Connection manually.


Welds are imported into the IDEA StatiCa Connection, however, the option for the welds AROUND is recommended as the best way to define weld.

Unfortunately, the software is not able to detect some welds, so the recommendation is to always check imported welds in IDEA StatiCa Connection. If the weld is not imported, then it’s better to generate weld for each plate in Tekla.


The stub member is supported and must be selected in the third step of the import selection procedure together with all joint elements (plates, bolts, welds) – “Select parts of connection”.


The anchoring import is not supported. A workaround is to add Base plate manufacturing operation in the IDEA StatiCa Connection manually after the import.
