  1. Figure 01 - Member Type "Dashpot" in RFEM

    Member Type "Dashpot"

    The member type "Dashpot" can be used for time history analyses in RFEM/RSTAB with the add-on modules RF-/DYNAM Pro - Forced Vibrations and RF-/DYNAM Pro - Nonlinear Time History. This linear viscous damping element considers forces dependent on velocity.

    With regard to viscoelasticity, the member type "Dashpot" is similar to the Kelvin-Voigt model which consists of the damping element and an elastic spring (both connected in parallel).

  2. Steels according to the Australian standard AS/NZS 4600:2005 in Material Library

    Material Library with Steels According to the Australian Standard AS/NZS 4600:2005

    The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
  3. TeamViewer in Help menu of RFEM and RSTAB

    Link to TeamViewer in Help menu of RFEM and RSTAB

    By opening the Help menu of RFEM and RSTAB, it is possible to directly access the TeamViewer. Customers with a Service Contract Pro can thus benefit from an easy and quick online support via video conference.

  4. Context menu in Navigator for entering a new surface

    Intuitive Graphical User-Interface

    A structure is created in the graphical user interface typical for CAD programs or by using tables. Right-clicking on graphical or navigator objects activates the shortcut menu, which facilitates creating or editing such objects. The user interface is operated intuitively so the structure and loading objects can be created in a minimal amount of time.

  5. Reinforcement settings of columns

    CONCRETE | Input

    After opening the program, you can define the standard and method according to which the design is performed. The ultimate and the serviceability limit state can be designed according to the linear and the nonlinear calculation method. Load cases, load combinations or result combinations are assigned to different calculation types then. In other input windows, you can define materials and cross‑sections. In addition, it is possible to assign parameters for creep and shrinkage. Creep and shrinkage coefficients are directly adjusted, depending on the age of the concrete.

    Support geometry is determined by means of design‑relevant data such as support widths and types (direct, monolithic, end, or intermediate support), redistribution of moments as well as shear force and moment reduction. CONCRETE recognizes the support types from the RSTAB model automatically.

    A segmented window includes the specific reinforcement data such as diameters, the concrete cover and curtailment type of reinforcements, number of layers, cutting ability of links and the anchorage type. In the case of the fire resistance design, it is necessary to define the fire resistance class, the fire‑related material properties as well as the cross-section side exposed to fire. Members and sets of members can be summarized in special "reinforcement groups", each defined by different design parameters.

    You can adjust the limit value of the maximum crack width in the case of crack width analysis. The geometry of tapers is to be determined additionally for the reinforcement.

  6. Material library with parameters relevant for calculation and design

    Cross-Section and Metarial Including Favorites

    Extensive cross‑section and material libraries facilitate modeling of plate and beam structures. These libraries can be filtered and extended by user‑defined entries. It is possible to import and analyze special cross‑sections from SHAPE‑THIN and SHAPE‑MASSIVE.

  7. Reducing stiffnesses in a load combination

    Modifying Stiffness / Considering Initial Deformations

    In the individual load cases or combinations, there is the option to modify the stiffness of materials, cross-sections, nodal, line and surface supports, as well as member end releases and line hinges for all or the selected members. Furthermore, it is possible to consider initial deformations from other load cases or load combinations.

  8. Dimensions and guidelines

    Displaying and Hiding Objects

    It is possible to specifically display or hide various objects such as nodes, members, supports, and others. You can dimension the model by using lines, archs, inclinations, or height elevations. Freely created guidelines, sections, and comments facilitate the input and evaluation. You can also display or hide guide objects individually.

  9. Graphical modeling using background layers

    Working with Layers

    There are various tools such as the object snap, user‑defined input grids, and guidelines, which facilitate the graphical input of structural data. DXF files can be imported as line models or used as a layer in the background in order to use specific snap points.

  10. Formula editor with a parameter list

    Optional Parametric Input

    In order to work with recurring structural systems efficiently, RSTAB provides the parametrized input. You can combine it with a parametrizable guideline method: Structures can be created using particular parameters and adjusted to a new situation by modifying the parameters.
