RFEM is in a class of its own

“I’ve used many FEA programs over the years and I would rank RFEM at the top. Very powerful with many options for modeling and displaying information while still being intuitive and easy to use from a common sense standpoint. In my opinion, RFEM is in a class of its own.”

Knowledge Base | American Standards

  1. RF-/STEEL AISC: Notional Loads to Represent Imperfections

    Notional Loads to Represent Imperfections

    In the AISC 360 – 14th Ed. C2.2, the direct analysis method requires the consideration of initial imperfections to be taken into consideration. The important imperfection of recognition is column out-of-plumbness. According to C2.2a, the direct modeling of imperfections is one method to account for the effect of initial imperfections. However, in many situations, the expected displacements may not be known or easily predicted.

  2. AISC: Direct Analysis Method and Stiffness Reduction

    Direct Analysis Method and Stiffness Reduction

    Requirements for the design of structural stability are given in the AISC 360 – 14th Ed. Chapter C. In particular, the direct analysis method provisions, which was previously located in Appendix 7 of the AISC 360 – 13th Ed., are described in detail. This method is considered an alternative to the effective length method which in turn eliminates the need for effective length (K) factors other than 1.0.
