The classification of cross-sections according to EN 1993-1-1 and EN 1993-1-5 can be carried out automatically in the RF-/STEEL EC3 add-on module. The maximum c/t ratios are specified in the standard for straight cross -section parts. There are no normative specifications for curved cross -section parts and therefore the cross -section classification cannot be performed for these cross -section parts.

Frequently Asked Questions (FAQ)
- What is the difference between the materials Isotropic Plastic 1D and Isotropic Nonlinear Elastic 1D?
- Is it possible to calculate and design "temporary structures"? What do I need for this?
- I design timber components. The deformations of load combinations deviate from the manual calculation exactly by the factor of the material partial safety factor. Why?
- I often edit the reinforcement provided by the program. Adjusting the reinforcement by using coordinates takes much effort and time if having several beams in the model. Is there any way to speed up the reinforcement editing?
- How is an inflatable object simulated in RFEM?
- Which programs can I use to calculate and design power plants?
- When defining my material, I get Warning No. 1136 and cannot continue working. How can I prevent this warning?
- How do you define the descriptions of various reinforcement results,such as the required reinforcement?
In my model, I have to consider construction stages with nonlinearities, so I have to work with the load combinations that are already included in the dead load.
I have several load combinations for the first and then also for the second construction stage to be analyzed and evaluated.
The load combinations from the first construction stage do not occur in the second construction stage.
I am not sure how to assign the load combinations in the construction stages (permanent or temporary).
- Why do I get such a small amount of reinforcement for the upstand beam? The amount of reinforcement for the downstand beams is significantly larger.
