RF-/TOWER Structure Add-on Module for RFEM/RSTAB
Generation of Lattice Tower Structures
The RF-/TOWER Structure add‑on module provides an innovative tool facilitating generation of geometrically complex 3D tower structures. It is possible to create lattice towers and radio masts by means of parameters.
In addition, RF‑/TOWER Structure can adjust the models created in RFEM or RSTAB.
-
Features
- Generation of triangular or rectangular tower types
- Access to the extensive material and cross-section library of RFEM/RSTAB
- Simple definition of geometry using tower segments
- Databases for vertical, horizontal, and inner bracing types
- Easy export of generated model data to RFEM/RSTAB
-
Input
First of all, it is necessary to select a tower type and the relevant materials and cross-sections. The tower geometry is defined by individual tower segments. Slopes can be defined via widths or relatively by geometry modification.
After entering tower legs, you can specify various stiffening of the lattice tower. It is possible to enter detailed specifications of horizontal girts, inner bracing, and vertical bracing of a tower with unequal sides. An extensive library including parametrized bracing types facilitates the input.
In addition, there is an interactive graphic in all input windows.
-
Generation
After generating the lattice tower model, the generated data is displayed in clearly-arranged tables. The output contains all information about member hinges and effective lengths.
In order to check the data graphically, there is the Viewer function providing a full screen display, which is also available in the input windows.
-
Data Export
Finally, it is possible to export the generated model to RFEM/RSTAB with a single mouse click.
All module data is included in the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.

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.
Members of triangular and quadrilateral lattice towers are allocated automatically provided that the lattice tower has been generated in the RF-/TOWER Structure and RF-/TOWER Equipment add-on modules.
However, it is also possible to allocate the members manually. In RF-/TOWER Design, you can use the effective lengths of truss members generated in the RF-/TOWER Effective Lengths add-on module. A manual input is also possible.
According to EN 1993-3-1 and EN 50341 standards, you can specify various bracing cases and support types for members of legs and bracing.
