AnswerThe DUENQ cross-section consists of several non-contiguous partial cross-sections, so that in DUENQ it is calculated according to the theory of stiffening systems. DUENQ also gives a hint before the calculation. The dimensioning of such cross sections is not possible in add-on modules such as RF / STEEL EC3, RF / ALUMINUM etc.In most cases, however, the cross-sectional parts should be connected to each other. The FAQ describes how this connection can be modeled.
In the case of Design Method 1, RF-/KAPPA uses the internal forces My and Mz at the respective design location. If the maximum values of My and Mz occur at different locations on the member, the corresponding internal forces may be applied. This is ensured by the design at different x-locations.
In contrast, the Design Method 2 always applies the maximum values of the moments over the entire member length, even if they do not occur at the same location on the member. Therefore, the component from bending is always constant for the entire member or continuous member in the design criteria.
The moment factor βm for determining the shape of the bending moments My and Mz is always applied with 1.1 or 1.0 (depending on the design method) for a result combination. The result combination represents an envelope, from which the shape of the moment factor cannot be clearly determined.

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.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
