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 fĂĽr geschraubte momententragfähige Kopfplattenverbindungen mit 4 Schrauben in einer Schraubenreihe auf der Grundlage der prEN 1993-1-1:2003; Deutscher Ausschuss fĂĽr Stahlbau DASt, DĂĽsseldorf
  • 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.

Thank you for your enquiry!

The merger of FRILO Software GmbH and DC-Software GmbH with ALLPLAN, completed and announced on 1 July, is leading to an increased volume of telephone and e-mail inquiries. In addition, necessary maintenance work in our CRM and ERP systems is causing temporary irregularities and delays in our operating processes. We, therefore, ask you to forgive us for the longer waiting times. We will endeavor to process your request as quickly as possible.

Thank you for your understanding.
