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.

Modeling a Kármán vortex street in RWIND
In RFEM 6 it is possible to save selected objects (as well as whole structures) as blocks and reuse them in other models. Three types of blocks can be distinguished: non-parameterized, parameterized, and dynamic blocks (via JavaScript). This article will focus on the first block type (non-parameterized).
This article describes how to create a user-defined antenna bracket to be used 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 3D type and define four nodes. The numbering and position of these nodes are very important here.
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.
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.
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:
-
DIN EN 1991-1-4 (Germany) -
CSN EN 1994-1-4 (Czech Republic) -
NA to CYS EN 1991-1-4 (Cyprus) -
DK EN 1991-1-4 (Denmark) -
NBN EN 1991-1-4 (Belgium) -
NEN EN 1991-1-4 (Netherlands) -
NF EN 1991-1-4 (France) -
SFS-EN 1991-1-4 (Finland) -
SIST EN 1991-1-4 (Slovenia) -
SR EN 1991-1-4 (Romania) -

SS-EN 1991-1-4 (Sweden) -
STN EN 1991-1-4 (Slovakia) -
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.
