Stress 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 frame and beam structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analyses.

Add-on Modules for RFEM and RSTAB

For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add‑modules available for the main program RFEM/RSTAB.

These modules allow you to perform nonlinear, stability and dynamic analyses as well as joint designs and form‑finding processes for cable and membrane structures.

Piping Stress Analysis

RF‑PIPING Design compares the existing pipe stresses with the allowable stresses according to EN 13480‑3, ASME B31.1, and ASME B31.3.

Design in RF‑PIPING Design is based on pipeline modeling in RF‑PIPING.

  1. Displaying Stress Components and Equivalent Stresses

    Displaying Stress Components and Equivalent Stresses

    RFEM 5.04.xx allows for graphical visualization of normal and shear stress of members (this feature is available only if the RF‑STEEL add‑on module is licensed).

  2. Stresses in RF-STEEL Surfaces for Weld Seam Design

    Stresses for Weld Seam Design

    In RF-STEEL Surfaces, it is possible to display the stresses relevant for the design of welds according to EN 1993‑1‑8, Figure 4.5, for example. When evaluating the stress ratio, the local axis system xyz of surfaces has to be taken into account.
