Design Software for Structural Steel and Timber Connections

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.

Design of Connections

Here you can find numerous add-on modules for the design of joints in steel and timber structures.

  1. Tension Connections in RF-/JOINTS Timber - Steel to Timber

    Tension Connections in RF-/JOINTS Timber - Steel to Timber

    In the case of tension connections with cleats subjected to unilateral loading, the external members (side timber) are loaded by an additional bending moment due to the eccentric load distribution. However, this fact is not mentioned in EN 1995‑1‑1 and is considered in the National Annex to DIN EN 1995‑1‑1 by the reduction of the tensile strength. This reduction depends on the pull‑off strength of the fasteners.

  2. DXF Export of Connection Geometry of RF-/JOINTS

    DXF Export of Connection Geometry

    Since the last update of RFEM/RSTAB, you can export the entire connection geometry in the DXF file format from RF‑/JOINTS. This is possible for all connection groups, both steel and timber. You can start the export in the ‘Results - Graphic’ window by clicking the new button below the graphics window.
