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.
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.
In this example, design resistance of an end plate according to EN 1993-1-8  is to be determined; the other components are not described here. To check the results, the dimensions of the connection IH 3.1 B 30 24 of Typified Connections  were used. The material S 235 and bolts with the strength 10.9 are used.
When designing bending-resistant connections from I‑beams, the connection is dissolved into the individual parts. For these basic components of a joint, there are separate formula calculators for load‑bearing capacity and stiffness. In RFEM and RSTAB, it is possible to design frame joints using the RF‑/FRAME‑JOINT Pro add‑on module.
In addition to the result tables, it is possible to create a three-dimensional graphics in RF‑/FRAME‑JOINT Pro and RF‑/JOINTS. This is a realistic representation of the connection to scale.
