To the equipment of a wind power station belongs a wind measurement tower, which is 90 m high and anchored by cables. It is supposed to have a lifetime of approx. 2 to 4 years.
Due to the temporary use, the tower must be erected with scaffold poles and guys, admitted for use by the supervising authority, in distances of 8 m. In addition to the dead load, it is especially important to take into account a wind load as the governing action. The foundation can be designed as a flat footing as well as a deep foundation.

After generating the effective lengths, the results are displayed in clearly arranged tables. You can modify the effective lengths manually there.
The Export function transfers the effective lengths to the RF-/TOWER Design add-on module for further calculation. The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
Finally, it is possible to export the generated model to RFEM/RSTAB with a single mouse click.
The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
The results are displayed in clearly arranged module windows. In addition to the design data, the results include all design-relevant parameters. A parts list is generated automatically during the calculation.
The complete module data are part of the RFEM/RSTAB printout report. The report contents and the extent of the results can be selected specifically for the individual designs.
When performing the design of tension, compression, bending, and shear loading, the module compares the design values of the maximum load capacity to the design values of the actions. If the components are subjected to both bending and compression, the program performs an interaction. You can determine the factors according to Method 1 (Annex A) or Method 2 (Annex B).
The flexural buckling design requires neither the slenderness nor the elastic critical buckling load of the governing buckling case. The module automatically calculates all required factors for the bending stress design value. RF-/TOWER Design determines the effective critical moment for lateral-torsional buckling for each member on every x-location of the cross-section.

Add-On
The Steel Joints add-on for RFEM allows you to analyze steel connections using an FE model. The FE model is generated automatically in the background and can be controlled via the simple and familiar input of components.
Add-On
The Structure Stability add-on performs stability analysis of structures. It determines critical load factors and the corresponding stability modes.
Add-On
The Stress-Strain Analysis add-on performs general stress analysis by calculating the existing stresses and comparing them with the limit stresses.
Add-On
The two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Furthermore, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
