Concrete Piers and Steel Pipe Rack Seismic Analysis, The Netherlands
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.

In RFEM, it is possible to modify stiffnesses for materials, cross -sections, members, load cases, and load combinations in many places.

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.
- Why do I get large differences for the design of a longitudinally stiffened buckling panel in comparison with the German and Austrian National Annex?
- How can I perform the stability analysis in RF‑/STEEL EC3 for a flat bar supported on edges, such as 100/5? Although the cross-section is rotated by 90° in RFEM/RSTAB, it is displayed as lying flat in RF‑/STEEL EC3.
- How can I create a curved or arched section?
- How are the signs for the release results of a line release and line hinges interpreted?
- How is the rotational stiffness of a buckling stiffener determined in PLATE‑BUCKLING?
- How are hot-dip galvanized components considered for fire resistance in the RF‑/STEEL EC3 add-on module?
- Is it possible to manually specify a longitudinal reinforcement for design in RF‑PUNCH Pro?
- Can I simulate the cracked state of a concrete cross-section for a bending beam with the "Isotropic Nonlinear Elastic 1D" material model?
- Why is the deflection of the reinforced concrete floor sometimes greater when selecting a larger basic reinforcement?
- How can I view the depth of the concrete compression zone in RF‑/CONCRETE?
