Concrete Piers and Steel Pipe Rack Seismic Analysis, The Netherlands
Customer Project
Witteveen+Bos performed a seismic analysis on an existing concrete foundation with piers located in the Netherlands. The connected steel pipe rack and piping system were also included in the analysis.Utilizing a multimodal response spectrum analysis in RFEM, Witteveen+Bos specified a unique response spectra to analyze the structural response induced by this seismic activity.

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.
- When calculating a cable using the STEEL EC3 add‑on module, there is the error message "Incorrect characteristic stresses for material No. 1! Please correct this in Table 1.2."
-
How can I retrospectively reduce the determined provided longitudinal reinforcement in RF‑CONCRETE Columns?
-
Is it possible to specify shrinkage effects as loads?
- Are effective length factors determined automatically from a model in the add-on modules for the aluminum and steel design or do I have to make adjustments?
-
Which units are specified in the result display of the support reactions (kN or kN/m)? A note about this is missing in the graphic.
In the case that the support reactions are given in kN/m, for which distance does the value apply?
- 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?
-
Is it possible to calculate with American steel cross-sections?
- Where do I find the setting to specify the entered structural component as a "wall" or "slab"?
- The four plates, identically loaded, show different negative moments at the point of support. Is this a mistake?
- How can I quickly model a chimney with reinforcement rings and stiffeners?
