Bolted Frame Corner
SRE-1
The SRE-1 program designs bolted connections of frames in steel structures and performs the necessary verifications of the structural safety and the welded connections.

SHOW MOREMaterial
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, ZĂĽrich 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.
