Warnings for welds and bolts connecting the same plates

Connection design combining welds and bolts or bolts and preloaded bolts is unsafe and not allowed by codes. The Connection application automatically informs you if such a workflow is used in a project to ensure proper, safe design.

The detailing check for bolts and welds in the IDEA StatiCa Connection application has been extended by new rules according to all available codes together with references for Eurocode.

Two potential situations for which you receive a warning message in the Detailing check are distinguished:

  1. The same two plates are connected by both bolts and welds.
  2. The same two plates are connected by both bolts and preloaded bolts.

1. Bearing bolts and welds

If the same two plates are connected by bolts with shear force transfer set as Bearing – tension/shear interaction and welds, a detailing warning message displays in the Bolts check section. 

2. Bearing bolts and preloaded bolts

If the same two plates are connected by bolts with shear force transfer set as Bearing – tension/shear interaction and bolts with shear force transfer set as Friction (preloaded bolts), a detailing warning message displays in the Preloaded bolts check section.

Why pay attention?

Using the above-mentioned approaches in your projects might affect the connection. 

The warning message provides you with recommendations. Raised attention to the design is advised but not unconditionally necessary. In other words, the connection won't fail because of the issue, however, you risk an incorrect design. 

Moreover, such workflows are not allowed by codes.
