  1. Creating a User-Defined Platform for Use in RF-/TOWER Equipment

    The following technical article describes the creation of a user-defined platform for use on a four-sided tower in the RF-/TOWER add-on modules. First, start with an empty model of the type 3D and define four nodes. The numbering and position of these nodes are very important here.

  2. Figure 01 - Structural System

    Nonlinear Time History Analysis Using the Example of a Tower Structure with Prestressed Cables

    There can be numerous nonlinearities in a structural system. In order to model them realistically in a dynamic analysis, the RF-DYNAM Pro - Nonlinear Time Histoey add-on module was developed. To explain how the add-on module works, the procedure is described below with an example.

  3. Figure 01 - Hall Frame as Basis for Surface Model

    Modeling Joints as Surface Model

    With RF-/FRAME-JOINT Pro, it is possible to design frame joints according to DIN 18800 or Eurocode 3. When considering non-standardized joints or taking a closer look at the joint and its behavior, it is recommended to use a modeling as surface model. The following article will show how such a model is created in principle.
  4. Figure 01 - Opening Block Manager with Catalogue Elements

    Modelling of Tower with Block Manager

    Lattice towers represent typical applications in steel construction. Examples for this special type of truss structures are antenna and overhead line towers, or columns for wind power stations, cable cars, and supporting frame constructions. The modelling can be done individually in RFEM and RSTAB by entering various tower elements. Furthermore, you can use different copy functions and parameterized input options. However, this procedure normally requires considerable effort. It is more comfortable to model such structures using pre-fabricated catalogue elements provided by the Block Manager. Those elements are automatically stored in the database during program installation. Thus, you can use tower segments, platforms, antenna brackets, cable ducts et cetera as parameterized building blocks for generating diverse tower structures.
  5. Manual Cross-Section Classification in RF-/TOWER Design

    Manual Cross-Section Classification

    In RF-/TOWER Design, it is now possible to classify cross‑sections manually according to Eurocode 3. This option may be useful when local buckling is prevented by the design and so the cross‑section has to be assigned to Class 3.

  6. New Option for Platform Connection in RF-/TOWER Equipment

    New Option for Platform Connection

    Platforms can be connected directly to leg members using the new “Leg Member Axis” option. Thus, it is not necessary to define the platform width or coupling member anymore.

  7. Serviceability Limit State Designs of Antennas in RF-/TOWER Design

    Serviceability Limit State Designs of Antennas

    As of the program version X.06.1103, it is possible to perform the serviceability limit state designs of antennas in RF‑/TOWER Design. You can activate this function under [Details] → “Serviceability.” Then, limit values can be adjusted in Window 1.10.2 Serviceability of Antennas.

  8. Additional Dead Loads on Platforms in RF-/TOWER Loading

    Additional Dead Loads on Platforms in RF-/TOWER Loading

    As of RFEM 5.04.0024 and RSTAB 8.04.0024, there is a new feature in RF‑/TOWER Loading, which allows you to define additional surface loads in a load case for dead loads, for example from grids on platforms.

  9. Antenna Ice Loads in RF-/TOWER Loading

    Antenna Ice Loads

    With the versions of RFEM 5.04.0024 and RSTAB 8.04.0024, it is possible to define the antenna ice loads in RF‑/TOWER Loading. The program provides values from manufacturer databases. In addition, you can define the ice loads manually or use the calculation based on the simplified geometry.

  10. Force Coefficients for Rounded and Square-Edged Profiles in RF-/TOWER Loading

    Force Coefficients for Rounded and Square-Edged Profiles

    RF-/TOWER Loading was extended with force coefficients for rounded profiles of four‑sided towers and square‑edged profiles of three‑sided towers. The force coefficients for rounded profiles are determined using the Reynolds number. Until now, you could only use the rounded profiles for four‑sided towers and the square‑edged profiles for three‑sided towers.
