First Steps with RFEM
Description
RFEM and RSTAB offer different options to model bored piles. One option is to display bored piles as single-valued supports or hinged columns. Another option is the realistic modeling while taking into account the soil by means of applying a member elastic foundation. The two following examples will describe it in detail. However, pile base resistance, skin friction and soil layers are not considered in this technical article.

Often, models are needed in several projects, like the purlin with columns and knee braces in this example. The dimensions can be changed directly in RFEM or RSTAB by shifting the nodes.
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.
- 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 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.
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- A rigid member should only be able to absorb tensile forces or only compressive forces. What are the options for considering these nonlinearities in the calculation?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- How do I display the nodal displacements graphically?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- When calculating deformations in RF‑CONCRETE Members, I see inconsistencies in the deflection diagram. Why?
- Why do I obtain great differences in results for both the deformation and the bending moments when applying inclination by using imperfection to a single member and an articulated set of members with the same total length?
