    Add-on Modules for Structural Steelwork

    Add-on modules supplement the functionality of the basic programs. With RF- / STEEL EC3, for example, you perform the design according to Eurocode 3 for the structure. The add-on module RF-STEEL Warping Torsion supplements this design according to Eurocode 3 with lateral-torsional buckling designs with up to 7 degrees of freedom, if it is not a standard case of EC3.

    Other more specialized applications such as the plastic design, the stability analysis according to the eigenvalue method or the generation of geometric equivalent imperfections and pre-deformed equivalent models are available. Single modules such as PLATE-BUCKLING support you in the design of rigid or stiffened plates. With the SHAPE-THIN add-on module, you can create any thin-walled cross-sections. The cross-section properties are determined and stress analyzes or plastic designs can be performed.

    Use the RF-JOINTS add-on modules to design hingeable or rigid connections.

    The CRANWAY one-way application is available for the design of crane runways.


    Dynamic Analysis

    If earthquake calculations or vibration analyzes are necessary for the building, the RF- / DYNAM Pro add-on modules provide suitable tools for determining natural frequencies and shapes, analysis of forced vibrations, generation of equivalent loads, or for the nonlinear time history analysis.

First Steps

First steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
