Warping Torsion Analysis Software

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

Analysis & Design of Frame/Beam/Truss Structures

Structural frame analysis and design software RSTAB contains a similar range of functions as RFEM, with special attention to frameworks. Therefore, it is very easy to use and for many years it has been the best choice for structural engineers.

Warping Torsion Second-Order Analysis with 7 Degrees of Freedom

RF-/STEEL Warping Torsion is an extension of the RF‑/STEEL EC3 add‑on module. It performs torsional‑flexural and lateral‑torsional buckling analysis of members according to the second‑order theory with 7 degrees of freedom and application of imperfections with regard to mode shapes.

  1. 1 - System and Loading

    Design of Tapered Single-Span Beam According to Eurocode 3

    The following article describes the design of a single‑span beam subjected to bending and compression, which is performed according to EN 1993‑1‑1 in the RF‑/STEEL EC3 add‑on module. Since the beam is modelled with a tapered cross‑section, thus not a uniform structural component, the design must be performed either according to General Method in compliance with Chap. 6.3.4 of EN 1993‑1‑1, or according to the second‑order analysis.

  2. Stability Analysis of Channel Sections

    Stability Analysis of Channel Sections

    The module extension RF‑/STEEL Warping Torsion of the RF‑/STEEL EC3 add‑on module allows you to design members with asymmetric cross‑sections. The new option is fully integrated in the design module and can be activated for sets of members.
