Structural Analysis Engineering 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.

Determination of Cross-Section Properties

Stand-alone programs SHAPE‑THIN and SHAPE‑MASSIVE are used for determining cross‑section properties of any cross‑section type, as well as calculation of stresses and design.

Both programs can be connected to RFEM and RSTAB so the SHAPE‑THIN and SHAPE‑MASSIVE cross‑sections are available in the RFEM or RSTAB libraries. It is also possible to import internal forces from RFEM and RSTAB to SHAPE‑THIN and SHAPE‑MASSIVE for further design.

Stand-Alone Software for Structural Engineering

The stand‑alone programs do not require installation of the main program RFEM or RSTAB.

CRANEWAY designs craneway girders according to EC 3 and PLATE‑BUCKLING performs buckling analysis of unstiffened and stiffened rectangular plates according to EC 3.

The RX‑TIMBER programs design glulam trusses, continuous beams, columns, purlins, frames, stiffening, and roofs of timber structures.

    Automatic Generation of Combinations

    The ‘Edit Load Cases and Combinations’ dialog box provides the option of the automatic generation of load and result combinations after selecting the corresponding combination expressions. In this clearly arranged dialog box, it is also possible to copy, add, or renumber load cases, for example.

    Furthermore, you can manage the load cases and combinations in Tables 2.1 – 2.6.

    Design of Deep Beams in RFEM

    When analysing structural components of reinforced concrete structures, it is often necessary to design deep beams. These are mainly used for window and door lintels, upstand and downstand beams, the connection between split-level slabs, and frame systems. If they are displayed as surfaces in RFEM, the evaluation of reinforcement results requires further steps.
