Known limitations for Tekla Structures

General recommendations

Please note that in IDEA StatiCa Connection the members are the only beam entities on which loads can be applied. Other beams are defined in a different way, as a stiffening member or set of plates. This rule goes in hand with the three-step import procedure:

    • In the first step, you should choose the node which will be representing the node of the joint.  
    • 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.

Cross-sections

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

Cross-section typeTekla parametric inputTekla library input
IXX
U-X
L XX
Circular hollowXX
Rectangular hollowXX
Rectangular plateX-
Cold-formed CXX

Parametric inputs are the user-defined dimensions of the required cross-section type. Library input is cross-section selected from the 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 the 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 and notches are supported and will be imported. 

 Welds on notched elements are not supported. If the welds are needed it must be defined in the IDEA StatiCa Connection manually.

Welds

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.

Stub

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”.

Anchoring

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

Rod connecting plate

A rod welded to a connecting plate is imported without the welds. This can be added in IDEA StatiCa Connection, but not just by a  weld operation. The connecting plate has to be deleted and replaced by a new Connecting plate operation assigned for the rod and the existing gusset plate.
