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 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.

Steel Joints | Stability Analysis Software
For the components of the joint, you can check whether stability failure is relevant (add-on structural stability for RFEM 6/RSTAB 9 required).
The critical load factor for all analyzed load combinations and the selected number of mode shapes is calculated for the connection model. The smallest critical load factor is compared with the limit value 15 from the standard EN 1993-1-1, clause 5. In addition, a user-defined adjustment of the limit value is possible. Furthermore, the corresponding mode shapes are displayed graphically as the result of the stability analysis.
For the stability analysis, an adapted surface model is used to specifically recognize the local buckling shapes. The model of the stability analysis, including the results, can also be saved and used as a separate model file.
- What is the maximum number of reinforcement groups that can be created in a design case in RF‑CONCRETE Surfaces?
- I would like to perform punching design of a floor slab. I have selected nodes for the design, but they are marked as invalid. Where did I make a mistake?
- Is it possible to display the deformation analysis of a surface (limit 0.5‰)?
