RF-TOWER Design assigns members of triangular and quadrilateral lattice towers automatically provided that the lattice tower was generated with the add-on modules RF-TOWER Structure and RF-TOWER Equipment. Of course, it is also possible to assign members manually for the design.

When the buckling lengths of the members used in lattice towers were determined with the add-on module RF-TOWER Effective Lengths, you can use the calculated data in the add-on module RF-TOWER Design. Manual data input is possible as well.

In accordance with the standards EN 1993-3-1 and EN 50341 you can specify different bracing cases and support types for the members of legs and bracings.

When analyzing stress for tension, compression, bending and shear, the program compares the design values of the maximum resistance with the ones of the actions. In case structural components are stressed by both bending and compression, RF-TOWER Design performs an interaction.

For the interaction formula you can choose whether you want to determine the factors according to method 1 (annex A) or 2 (annex B).

For the flexural buckling design neither the slenderness nor the elastic critical buckling load of the governing buckling case must be specified. The add-on module calculates all required factors for the design value of the bending load automatically. The ideal critical moment for lateral torsional buckling is determined by the program itself, for each member on every x-location of the cross-section.

The results are shown in clearly-arranged module tables. In addition to the design results the output includes all design-relevant parameters. Furthermore, a parts list is generated automatically during the calculation. Finally, it is possible to export the results to a spreadsheet program.
