Glass Chandeliers at Keystone Mall, USA
Four different point-supported glass chandeliers are focal points of the newly renovated shopping mall at Keystone, Indianapolis, USA.Each chandelier consists of hanging glass plates, which are point-supported from brackets on stainless steel rings.

The largest chandelier is elliptical with a major diameter of 36 feet. The 11 ft tall glass plates are oriented in angles to each other, fanning outward towards the bottom.
The RSTAB model accurately followed the assembly of the physical parts, including the tiny details of the connectors. This allowed reliable prediction of the flexible deformations and the dynamic behavior.
The decorative glass is illuminated at night with intense colorful light of blue and red. The glass also plays an active role in the overall structural system, stabilizing the rings against rotation.

The RF-/STEEL EC3 add-on module automatically transfers the buckling line to be used for the flexural buckling analysis for a cross-section from the cross-section properties. In particular for general cross -sections, but also for special cases, the assignment of the buckling line can be adjusted manually in the module input.

SHAPE-THIN determines the effective cross-sections according to EN 1993-1-3 and EN 1993-1-5 for cold-formed sections. You can optionally check the geometric conditions for the applicability of the standard specified in EN 1993‑1‑3, Section 5.2.
The effects of local plate buckling are considered according to the method of reduced widths and the possible buckling of stiffeners (instability) is considered for stiffened sections according to EN 1993-1-3, Section 5.5.
As an option, you can perform an iterative calculation to optimize the effective cross-section.
You can display the effective cross-sections graphically.

- In the calculation parameters of a load case or load combination, it is possible to activate various stiffness factors. What exactly is behind this?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
- Why is not there one load for each country in the online service "Geo-Zone Tool: Snow, Wind, and Seismic Zone Maps"?
- Why do I get high differences when designing a longitudinally stiffened buckling panel compared to the German and Austrian National Annexes?
- How can I perform the stability analysis for an edgewise supported flat steel, for example 100/5, in RF-/STEEL EC3? Although the cross-section is rotated by 90 ° in RFEM/RSTAB, it is displayed lying flat in RF-/STEEL EC3.
