    Frame & Truss Analysis Software RSTAB 9 | Features

    We are constantly developing Dlubal's structural analysis software so that you can benefit from powerful features. Use the successful frame and truss analysis software RSTAB for the calculation of 2D or 3D frame and truss structures made of steel, concrete, timber, aluminum, or other materials.

    RSTAB allows you to quickly and easily define the structural model and then calculate the internal forces, deformations, and support reactions. Add-ons are available for design checks, allowing you to consider material and code-specific conditions.

    Powerful Features in RSTAB 9

    RSTAB 9 offers numerous helpful features that support you in the structural analysis of frame & truss structures.

    Main Features in RSTAB 9

    Discover powerful tools that enhance modeling and analysis.

    • Wind Simulation (RFEM or RSTAB Environment)

      Discover the new features in RFEM and RSTAB for determining wind loads using RWIND:

      • Helpful load wizards for generating wind load cases with different flow fields in different wind directions
      • Wind load cases with freely assignable analysis settings, including user-defined specifications for wind tunnel size and wind profile
      • Comprehensive display of the wind tunnel with input wind profile and input wind turbulence intensity profile
      • Visualization and use of RWIND simulation results
      • Global definition of a terrain (horizontal planes, inclined plane, table)
    • Integration of All Add-ons

      Discover the advantages of working with the wide range of add-ons for RFEM 6 and RSTAB 9. All add-ons are integrated into the programs. This allows the individual program components to interact with each other and ensures that your calculations and design checks are carried out smoothly. Examples include the determination of the ideal tilting moment of timber beams using the “Warping Torsion (7 DOF)” add-on or the consideration of staggered shape finding processes using the “Construction Stages Analysis (CSA)” add-on.

    Import of Construction Site for Load Determination

    Always keep an eye on the natural conditions of your construction site by defining it on a digital map. The address data (including the altitude) as well as the snow load zone, wind zone, and seismic zone are imported automatically. The load wizard also uses these data.

    The map is also displayed with the construction site marked in the "Model Parameters" tab.

    What other features would you expect?

    The RSTAB 9 program is constantly being developed and new features are being added. Discover what else it can provide and take your projects to a new level!

    Calculation Diagrams in RFEM

    Creating Calculation Diagrams

    Do you want to create calculation diagrams? With RFEM and RSTAB, this works globally and without any problems. Use calculation diagrams to record and display a relation between the various calculation results.

    Overlapping Display of Results of Two Similar Members

    Improved Result Diagram Window

    Discover the features in the result diagram window, which allows parallel work in both the diagram window and the model, and offers an optional overlapping display of results, such as several similar structural components in one image.

    Unit Stresses of Steel Cross-Section

    Cross-Section Unit Stresses

    Make sure that nothing collapses: To enable you to estimate the load-bearing capacity of member cross-sections, display the unit stresses (related to N = 1 kN, My = 1 kNm, and so on).

    Defining Member Representatives for Concrete Design

    Member and Member Set Representatives

    Define representatives for members with identical properties to easily display results in tables.

    Snow Load Wizard

    Extension of Snow and Wind Load Wizards

    Discover the new features of the snow and wind load wizard: loading of hybrid models (RFEM only), connection to the Geo-Zone tool (depending on the construction site), and deactivation of surface sides.

    Clipping Box

    Clipping Box

    Keep an eye on what is really relevant to your project. In addition to the clipping plane, you can now define a clipping box. This allows you to hide irrelevant objects around a focus point.
