Interpolation based on a taper in steel construction
Video
First Steps with RFEM
Description
Since we civil engineers have to deal with tables very often, we would like to show you in this short video how to interpolate.
As an example, we look at a tapered member in RSTAB. The member is 1.81 m long and has a height of 500 mm at the member start and of 300 mm at the end.
We show you how to find out the member's height at a specific location by using interpolation.
Then, we verify the result in RSTAB.
Small deviations occur because the model's members are eccentrically connected to each other in RSTAB.
Have fun!

Modeling Tapers for Hall Frames
Tapers are often done using cut beam sections. When modeling, however, you have to consider some things for the checks of cross‑sections and stability.

Depending on stiffness, mass, and damping, structures react differently to wind action.
Frequently Asked Questions (FAQ)
- How can I retroactively change the cross-sections of a tapered beam consisting of several members?
- Does the load generation also work for curved members?
- I would like to calculate and design "temporary structures." What do I need for this?
- 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?
- 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?
- Which programs can I use to calculate and design power plants?
- Which filter settings should be selected in the material library for concrete in order to perform design in RF‑CONCRETE according to the Swedish National Annex? In RFEM, there is no Swedish standard group available for the selection.
- I have analyzed two models of an inclined bored pile as a support with defined spring stiffness. A surface that can be moved horizontally (globally) is used for the force transmission. The bored pile in Model A is a support inclined by 15° with a spring stiffness of 2,000 kN/m in the axial direction. The bored pile of Model B is a support with the defined spring stiffnesses, divided into the respective horizontal and vertical components. The value of the spring stiffness is always the same (2,000 kN/m). In my opinion, both models are equivalent. Why are there different results in the deformation anyway?
- I design a cross-section created in the SHAPE‑THIN program by using the RF‑STEEL EC3 add-on module, but the program shows the error message "ER006 Invalid type of c/t-part for cross-section of type General." What can I do?
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
