Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
The following article describes how to create a user-defined antenna bracket which will 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 type 3D and define four nodes. The numbering and position of these nodes are very important here.
There can be numerous nonlinearities in a structural system. In order to model them realistically in a dynamic analysis, the RF-DYNAM Pro - Nonlinear Time Histoey add-on module was developed. To explain how the add-on module works, the procedure is described below with an example.
With RF-/FRAME-JOINT Pro, it is possible to design frame joints according to DIN 18800 or Eurocode 3. When considering non-standardized joints or taking a closer look at the joint and its behavior, it is recommended to use a modeling as surface model. The following article will show how such a model is created in principle.
Lattice towers represent typical applications in steel construction. Examples for this special type of truss structures are antenna and overhead line towers, or columns for wind power stations, cable cars, and supporting frame constructions. The modelling can be done individually in RFEM and RSTAB by entering various tower elements. Furthermore, you can use different copy functions and parameterized input options. However, this procedure normally requires considerable effort. It is more comfortable to model such structures using pre-fabricated catalogue elements provided by the Block Manager. Those elements are automatically stored in the database during program installation. Thus, you can use tower segments, platforms, antenna brackets, cable ducts et cetera as parameterized building blocks for generating diverse tower structures.
In RF-/TOWER Design, it is now possible to classify cross‑sections manually according to Eurocode 3. This option may be useful when local buckling is prevented by the design and so the cross‑section has to be assigned to Class 3.
Platforms can be connected directly to leg members using the new ‘Leg Member Axis’ option. Thus, it is not necessary to define the platform width or coupling member anymore.
As of the program version X.06.1103, it is possible to perform the serviceability limit state designs of antennas in RF‑/TOWER Design. You can activate this function under [Details] → ‘Serviceability’. Then, limit values can be adjusted in Window 1.10.2 Serviceability of Antennas.
As of RFEM 5.04.0024 and RSTAB 8.04.0024, there is a new feature in RF‑/TOWER Loading, which allows you to define additional surface loads in a load case for dead loads, for example from grids on platforms.
With the versions of RFEM 5.04.0024 and RSTAB 8.04.0024, it is possible to define the antenna ice loads in RF‑/TOWER Loading. The program provides values from manufacturer databases. In addition, you can define the ice loads manually or use the calculation based on the simplified geometry.
