Whether you see the selection in the Results navigator or not depends on the settings for the serviceability limit state design.In the settings for the serviceability limit state design, you can find the "Increase the required longitudinal reinforcement automatically for serviceability limit state design" option.Figure 01 - Settings for Analytical Method of Serviceability Limit State Design in RF-CONCRETE SurfacesIf activating the automatic increase of the longitudinal reinforcement, the "Limit State" entry is only available in the Results navigator.
AnswerThis may be related to the curtailment of the provided reinforcement.If no curtailment is activated, a uniform reinforcement is designed across the entire structure (Figure 01).
The curtailment of the reinforcement can be activated in the "Longitudinal Reinforcement" tab of the add-on module (Figure 02).
After activating the curtailment, it is possible to define the number of areas. The higher is the number of areas, the more precisely can the provided reinforcement follow the distribution of the required reinforcement (Figure 03).
AnswerIn RF-CONCRETE Surfaces, the "top" or "bottom" position is controlled by the orientation of the area's local coordinate system.See also the FAQ000740This means for a wall that As, below or As, above can either be the reinforcement on the outside or inside depending on the orientation of the local z-axis.Both values must be taken into account for the reinforcement planning.So the sum of A s, below + A s, above .
AnswerIn RF-CONCRETE Members (RFEM) or CONCRETE (RSTAB), the offset is considered by default when determining the provided reinforcement.The difference between required reinforcement with and without offset is displayed when you open the Results navigator window:- A s, -z (top)- A s, + z (bottom)- A s, -z (top), comp.- A s, + z (bottom), comp.display results.In A s, -z (top), comp. and A s, + z (bottom), comp. the offset is included.See Figure 1.For the provided reinforcement in RF-CONCRETE Members or CONCRETE, the program considers the anchorage length for "straight" iron by default. The input can be found in the input window 1.6. See Figure 2.The anchoring length becomes from A s, -z (top), comp. and A s, + z (bottom), comp. determines. Thus, the offset is also included here.

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. ”
