How to take the reinforcement into account in anchor design?

Anchor design in Connection

For some time now, it has been possible to model and assess the anchoring of steel beams/columns to a concrete block in IDEA StatiCa Connection. The ability to model anchors with hooks has been added to the recently released version 24.1. The empirical formulas from the Eurocode (EN 1992-4 and EN 1993-1-8) are used to assess the different failure modes of anchors and concrete. However, due to the lack of information on some types of anchors and the fact that reinforcement in the concrete block cannot be taken into account, some failure modes cannot be fully assessed. However, the user is advised of the following statement.

3D CSFM in Detail application

Previously, users had to add manual calculations for some cases. To eliminate these deficiencies, it is now possible to export the model from Connection to Detail. This involves transferring the geometry and parameters of the concrete block, footplate and anchors including the applied load. In Detail, it is then possible to model the reinforcement into the concrete block and perform a non-linear finite element calculation (3D CSFM).

The checks are then not based on standard Eurocode formulas, but directly assess the stresses and strains in the concrete and reinforcement determined by taking into account the code-compliant material characteristics.

In this webinar, we will present the entire anchoring design workflow and explain the modeling specifics in a practical demonstration.
