KB 001768 | AISC 341-16 Moment Frame Connection Strength in RFEM 6
First Steps with RFEM
Moment frame design according to the AISC 341-16 is now possible in the Steel Design add-on of RFEM 6. The seismic design result is categorized into two sections, member requirements and connection requirements. This article covers the required strength of the connection. An example to compare the result between RFEM and the AISC Seismic Design Manual  is presented.

CSA S16:19 Stability Considerations and the New Annex O.2
The CSA S16:19 Stability Effects in Elastic Analysis method in Annex O.2 is an alternative option to the Simplified Stability Analysis Method in Clause 8.4.3. This article will describe the requirements of Annex O.2 and application in RFEM 6.
- The load distribution on my members looks different when using the Load Transfer surface vs. the Load Wizards. What is the reason?
- My beam has a continuous lateral support and therefore lateral torsional buckling (LTB) is not a concern. How do I define the effective length?
- I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
