Marie Curie School’s Timber and Steel Structures Preliminary Design in Fontoy, France
The general contractor Demathieu Bard Construction awarded the Dlubal customer BET Moselle Bois to carry out the timber and steel structures preliminary design. The projects are part of the Marie Curie School located in Fontoy of the Moselle district.

RFEM Data for the Bicycle Shelter
New School Building Entrance
The school’s entrance wood structure is a half glued-laminated timber frame. Web plate connections were used between the posts and the rafters. In the upper section, the rafters are supported at one end on a concrete wall.
The timber posts include a pinned support to the concrete floor with members spanning between each post.
A longitudinal beam further supports the roof purlins.
New Bicycle Shelter
The bicycle shelter includes a steel frame with circular columns pinned at the ground level. The purlins and rafters are I-sections. The columns are rigidly connected to the rafters. An I-section plate is welded at the top of the column to secure connection with the purlins.
The frames are oriented in the longitudinal direction and the purlins are fixed on each side.
A vertical slat cladding at the roof level is attached to the top purlins and bottom plates.
BET Moselle Bois carried out the 3D frame preliminary design utilizing the structural analysis software RFEM. The required designs according to Eurocode 5 for the timber structure and Eurocode 3 for the steel structure were performed with the RF-TIMBER Pro and RF-STEEL EC3 add-on modules.

Structure stability is not a new phenomenon when referring to steel design. The Canadian steel design standard CSA S16 and the most recent 2019 release is no exception.
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.

- Why the results of members and set of members differ in the design?
Why are my steel members not being designed for stability in RF-STEEL AISC?
- My section is classified as Class 4 and non-designable in RF-/STEEL CSA. However, my manual calculation shows a different class. Why the difference?
- I have defined temperature loads, strain loads, or a precamber. As soon as I modify stiffnesses, the deformations are no longer plausible.
- Can the properties, such as B. the cross -section or the surface thickness as well as the material of a surface of an existing element for a new element?
- I am trying to manually check the deformations from the CRANEWAY add-on module. However, I obtain great deviations. How to explain the differences?
- In RF-/TIMBER AWC and RF-/TIMBER CSA, I receive the error that says torsion limit exceeded. How do I bypass this error message?
- Why is the strength always reduced by the kmod value of 0.6 during the calculation in the RF‑LAMINATE add‑on module, although I have load combinations with variable loads?
- Can I consider a reduction of the stiffness according to the German regulation NCI NA.5.9 in TIMBER Pro?
- What should be considered when using a failure of columns under tension in the RF‑/DYNAM Pro – Equivalent Loads add-on module?
