  1. Figure 01 - Elastic Foundation

    Modeling and Calculating a Floating Body with RFEM

    To correctly model and calculate floating bodies (special rafts, pontoons, floating jetties, dredgers, floating houses, inflatable islands, floating cranes, houseboats, et cetera), a two-stage calculation is necessary.

  2. Figure 01 - Generate 3D Cell

    Modeling Containers by Generating a 3D Cell

    With the function "Generate Model - Members" → "3D Cell", it is very easy to generate containers (shipping containers, office containers, mobile homes, etc.) with regular and irregular distribution of the cells.
  3. Figure 01 - Load Case 1

    Warping Torsion Analysis According to AISC Design Guide 9

    The design of a torsional loaded beam according to AISC Design Guide 9 will be shown based on a verification example. The design will be performed with the RF-STEEL AISC add-on module and the RF-STEEL Warping Torsion module extension with 7 degrees of freedom.
  4. Figure 01 - Original Structure

    Consideration of Possible Contact Between Overlapping Members

    From time to time it happens that two intersecting beams overlap at a short distance.
  5. Figure 01 - Template Explorer

    Using Templates in VCmaster

    By using an interface, it is possible to export the RFEM/RSTAB printout report to VCmaster and continue editing there. VCmaster is a word processing program for engineers.

  6. Figure 01 - Structure with Loading

    Consideration of Holes in Tension Design

    For the tension design according to Clause 6.2.3 EN 1993-1-1, the following formulas are given to determine the tension resistance.

    $\begin{array}{l}\mathrm{Equation}\;6.6:\;{\mathrm N}_{\mathrm{pl},\mathrm{Rd}}\;=\;\frac{\mathrm A\;\cdot\;{\mathrm f}_\mathrm y}{{\mathrm\gamma}_{\mathrm M0}}\\\mathrm{Equation}\;6.7:\;{\mathrm N}_{\mathrm u,\mathrm{Rd}}\;=\;\frac{0.9\;\cdot\;{\mathrm A}_\mathrm{net}\;\cdot\;{\mathrm f}_\mathrm u}{{\mathrm\gamma}_{\mathrm M2}}\end{array}$
  7. Figure 01 - Generating wind loads

    Consideration of the Correlation with Wind Loads

    If the wind load for buildings or structures is to be determined by the simultaneous assumption of aerodynamic pressure and suction coefficients on the windward and leeward sides of the building, the correlation of the wind pressure on zones D and E of the wall surfaces may be taken into account.
  8. Figure 01 - Export to VCmaster

    Export to VCmaster

    Printout reports created in RFEM and RSTAB can be transferred to VCmaster using a direct interface and further processed there. VCmaster (formerly BauText) is a word processing program for engineers. Calculations, drawings, photos and documents from various sources can be easily compiled, managed and used again with VCmaster.

  9. Figure 01 - Moving Load Library According to AASHTO and AREMA Standards

    Moving Loads According to AASHTO Standard

    Design loads specified in the AASHTO Bridge Design Specification are available in the RF‑MOVE Surfaces moving load library. Design Truck (HS‑20), Tandem, Type 3, and Overload are available options.

  10. Figure 01 - Virtual Joists and Virtual Joist Girders in Cross-Section Library

    SJI Virtual Joists Available

    The Steel Joist Institute (SJI) has previously developed Virtual Joist tables to estimate the section properties for Open Web Steel Joists. These Virtual Joist sections are characterized as equivalent wide-flange beams which closely approximate the joist chord area, effective moment of inertia, and weight. Virtual Joists are also available in the RFEM and RSTAB cross‑section database.
