Consideration of the net cross-section for tensile stress according to EN 1993-1-1
When connecting tension -loaded components with bolted connections, the cross -section weakening due to the bolt holes must be considered in the ultimate limit state design. The following article describes how the design of the tension resistance according to DIN EN 1993-1-1 can be performed with the net cross-section area of the tension member in the RF-/STEEL EC3 add-on module.

Structural Analysis Models for Download
Download numerous structural models (for example, RFEM, RSTAB, or RWIND files) to utilize them for training purposes or for your projects.
Frequently Asked Questions (FAQ)
- Is it possible 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?
- How is an inflatable object simulated in RFEM?
- 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?
-
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 - 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?
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
