The most important formulas of a civil engineer Part 2
Video
First Steps with RFEM
Description
In the second part we extend our selection of the most important formulas for civil engineers to provide you with even more useful formulas and tools for your everyday life as civil engineers and students.
This time, we go into detail and look at more complex cross-sections and quick estimations.
Find the first part in our channel and on the Dlubal website.

Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
Frequently Asked Questions (FAQ)
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- Where do I find the setting to specify the entered structural component as a "wall" or "floor"?
- "During the calculation of material non-linearity, the material with a decreasing branch of the diagram can be calculated with one load increment only." Why do I get this error?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Are the models and presentations from Info Day 2019 freely available, and can you send them to me?
- Why are the values of a column base, head or center on the individual columns only displayed partially for the results from the calculation in RF‑CONCRETE Columns?
- I am trying to manually check the deformations from the CRANEWAY add-on module. However, I obtain great deviations. How to explain the differences?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
- Why is there no stability analysis displayed in the results despite the activation of the stability analysis in RF‑/STEEL EC3?
- How can I model and design a crane runway girder with Dlubal Software?
