RF-/TOWER Loading | Features

  • Consideration of the self-weight of a tower, including equipment
  • Wind load distribution to exposed and shaded tower faces, or user-defined distribution
  • Determination of wind loads applied to tower and equipment, especially for structures prone to vibration (gust factor)
  • Assignment of surface and concentrated loads to platforms
  • Optional reduction of total wind load on selected objects
  • Determination of ice loads for icing classes G and R with preset ice thickness and ice flag lengths of frost
  • Generation of variable load cases with surface and maintenance loads

RF-/TOWER Loading | Input

The RF-/TOWER Loading add-on module meets the requirements of EN 1991-1-4 / DIN EN 1993-3-1, DIN 1055-4, DIN 4131:1991-11, and DIN V 4131:2008-09. These standards include specifications of dead, wind, maintenance/technician and ice loads (ISO 12494 or DIN 1055-5), as well as variable loads. The standard specifications are preset or available in the libraries.

For the generation of wind loads according to Eurocode, the National Annexes (NA) of the following countries are available:

  • DE | Flag DIN EN 1991-1-4 (Germany)
  • CS | Flag CSN EN 1994-1-4 (Czech Republic)
  • Cyprus Flag NA to CYS EN 1991-1-4 (Cyprus)
  • Denmark Flag DK EN 1991-1-4 (Denmark)
  • Belgium Flag NBN EN 1991-1-4 (Belgium)
  • Flag of the Netherlands NEN EN 1991-1-4 (Netherlands)
  • France Flag NF EN 1991-1-4 (France)
  • Finland Flag SFS-EN 1991-1-4 (Finland)
  • Slovenia Flag SIST EN 1991-1-4 (Slovenia)
  • Romania Flag SR EN 1991-1-4 (Romania)
  • Singapore Flag SS EN 1991-1-4 (Singapore)
  • Sweden Flag SS-EN 1991-1-4 (Sweden)
  • Slovakia Flag STN EN 1991-1-4 (Slovakia)
  • Italy Flag UNI EN 1991-1-4 (Italy)

It is possible to generate individual load situations: You can set the wind pressure, wind direction, or ice loads manually, or import them from tables.

RF-/TOWER Loading | Generation

After generating the loads, you can check the results in clearly arranged tables. The output includes all information about the generated load cases and loads due to self-weight, wind load, and ice load. All loads are itemized in structural objects and equipment.

RF-/TOWER Loading | Data Export

The generated loads can be transferred easily to RFEM/RSTAB in order to superimpose other load cases. 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.
