Design of a welded truss
This technical article deals with the component and cross-section designs of a welded truss in the ultimate limit state. Furthermore, the deformation analysis in the serviceability limit state is described.

Structural Analysis Models to Download
You can download here a wide range of structural models (for example, RFEM, RSTAB, or RWIND files) that you can use for training purposes or for your projects.
Frequently Asked Questions (FAQ)
- 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?
- How is an inflatable object simulated in RFEM?
- 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?
- 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?
- In the filter settings for the values on surfaces, you can display a certain range of results and hide the rest. How can I hide a certain range of values and display the rest?

In the current program version of RFEM, the calculation does not converge anymore. I have already calculated the model in different RFEM versions:
RFEM 5.21.02 - Calculation converges
RFEM 5.23.02 - Calculation does not converge
RFEM 5.24.01 - Calculation does not converge - 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?
