Frame with Foundation with Anchor Bolts
Table 3.1 of EN 1993‑1‑8:2010‑12 defines the nominal values of the yield strength and the ultimate limit strength of bolts. The bolt classes given here are 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 10.9. The note for this table states that the National Annex may exclude certain bolt classes. For the NA of Germany, these are the bolt classes 4.8, 5.8, and 6.8.
Frame with Foundation Considering Horizontal Friction
According to Clause 6.2.2 (6) of EN 1993‑1‑8:2010‑12, you can apply friction using the friction coefficient to design the shear capacity.
System and Loading According to [1]
The product range of Dlubal Software contains various modules for design of steel and timber connections. The RF-/JOINTS Steel – Column Base add-on module allows you to analyse footings of hinged or restrained steel column bases. The fastener selection, foundation geometry, and material quality are crucial for the cost-effective and safe design of the column base.
KB 001875 | AISC 341-22 Moment Frame Member Design in RFEM 6
The three types of moment frames (Ordinary, Intermediate, Special) are available in the Steel Design add-on of RFEM 6. The seismic design result according to AISC 341-22 is categorized into two sections: member requirements and connection requirements.

Steel Design | Seismic Force-Resisting System Design Overview
  • Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
  • Ductility check of the width-to thickness ratios for webs and flanges
  • Calculation of the required strength and stiffness for stability bracing of beams
  • Calculation of the maximum spacing for stability bracing of beams
  • Calculation of the required strength at hinge locations for stability bracing of beams
  • Calculation of the column required strength with the option to neglect all bending moments, shear, and torsion for overstrength limit state
  • Design check of column and brace slenderness ratios
Seismic in Steel Design Add-on | Results

The seismic design result is categorized into two sections: member requirements and connection requirements.

The "Seismic Requirements" include the Required Flexural Strength and the Required Shear Strength of the beam-to-column connection for moment frames. They are listed in the ‘Moment Frame Connection by Member’ tab. For braced frames, the Required Connection Tensile Strength and the Required Connection Compressive Strength of the brace are listed in the ‘Brace Connection by Member’ tab.

The program provides the performed design checks in tables. The design check details clearly display the formulas and references to the standard.

Feature 002733 | AISC 341-16 Seismic Design for Steel Members

In the Concrete Design provides an option to perform seismic design according to AISC 341-16 for steel members.

Five SFRS types (Seismic Force-Resisting Systems) are available for this.

Frequently Asked Questions (FAQ)
How do I define a plastic hinge in RFEM 6?
How can I exchange data between RFEM 6 / RSTAB 9 and IDEA StatiCa?
How can I generate an area load on members via cells in RFEM 6 or RSTAB 9?
In the Steel Design add-on, I have set the boundary conditions in such a way that the I-beam flange is restrained against the horizontal displacement. I then calculated the critical load factors using the Structure Stability add-on, but with no effect on the critical load factor value. What is the reason for this?
Can I estimate which minimum cross-sections I should use before starting to design my model?
How do I define a pipe as a shear key in RF‑/JOINTS Steel – Column Base add-on module?
