Structural Bridge Analysis and Design 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 beam, frame and truss structures. Therefore, it is very easy to use and for many years it has been the best choice for structural analysis.

More Add-on Modules for Bridge Construction Design

Depending on the material used in bridge constructions, you can find more useful add-on modules for structural analysis and design under the Steel Structures, Concrete Structures and Timber Structures industries.

  1. Moving Loads with RF-MOVE Surfaces

    Moving Loads

    Moving loads can be easily generated with RF‑MOVE Surfaces. A library is available with load models as defined in the Eurocode 1, Part 2. The input of step size, offsets at start and end, and the distance to a reference line makes it possible for the user to generate user‑defined load models and also influence the number of generated load cases. RF‑MOVE Surfaces generates load cases and optional also a result combination as envelope of all results.

  2. Combinatorics for Road Bridge Construction According to EN 1990 + EN 1991-2: Specification of Load Cases in Action Category gr1 to gr5

    Combinatorics for Road Bridge Construction According to EN 1990 + EN 1991-2: Specification of Load Cases in Action Category gr1 to gr5

    If you select the combinatorics according to EN 1990 + EN 1991‑2 and define a load case in the action category gr1a, gr2, or gr5, you have to additionally define in the program which load model should be taken as a basis for the load case. This information is crucial for defining combination rules for automatic combinatorics according to EN 1990 + EN 1991‑2. In the gr1a category, you can select TS (LM1), UDL (LM1) or pedestrian and cycle track, for example. TS (LM1) is preset by default. In the gr2 category, it is possible to select breaking and acceleration forces or centrifugal forces as a specification.
