Material

Different materials can be selected for the beam and the column. The following materials are available:

Structural steel: S235, S275, S355, S450
Annealed steel (S275N – S460N)
Thermo-steel (S275M – S460M)
Weathering steel (S235W – S355W)
High-temperature steel (S460Q – S460QL1)
Hollow section, hot-finished (S235H – S355H)
Hollow section, hot-finished, fine-grain (S275NH – S460NH)
User-defined steel

Structural system

Available systems:

Beam to continuous column (T-joint)
Beam to column ending at the corner (knee joint)
Column to beam ending above the column (K-joint)
Column to continuous beam (rotated T-joint)
T-joint with haunch on one or both sides and inclined beam
Knee joint with haunch on one side and inclined beam
Knee joint with additional tension plate in the bolted connection, optionally also bolted to a top plate
Arrangement of diagonal stiffeners or a web plate on one side in the shear panel area
Arrangement of web stiffeners in the load-transferring component is possible

Cross-sections:

I-sections as standard shapes
User-defined I-sections

Loads

Design internal forces from axial force, moment and shear force
Multiple combinations of design internal forces can be entered

Fasteners

Bolts (black bolts and fit bolts)
Sizes: M12, M16, M20, M22, M24, M27, M30, M36
Strength classes: 4.6; 5.6; 8.8; 10.9

Design

The calculation of joints with two vertical bolt rows is based on the component method as per DIN EN 1993-1-8. For the verification of butt plate joints with four vertical bolt rows, the model described in the following publications is used:

Research Report 3/2009: Entwicklung eines Bemessungsmodells für geschraubte momententragfähige Kopfplattenverbindungen mit 4 Schrauben in einer Schraubenreihe auf der Grundlage der prEN 1993-1-1:2003; Deutscher Ausschuss für Stahlbau DASt, Düsseldorf
WAGENKNECHT: Stahlbau Praxis nach Eurocode 3, Band 3 Komponentenmethode, 2nd edition; Beuth Verlag GmbH, Berlin, Wien, Zürich 2017

Either the elastic or plastic cross-sectional resistance is verified. The verification of the weld seam limit stresses is performed using the simplified method.
