Macallan Distillery, Scotland
After three years of construction, the new production of the renowned Scottish whiskey maker Macallan was completed in May 2018. The company building has a spectacular roof structure, which fits perfectly into the surrounding landscape. The green roof spans a length of more than 656 ft. It consists of five domes with a tapered canopy.

StructureThe overall dimensions of the new distillery amount to 679 ft x 207 ft. The roof height varies from approximately 10 ft on the eave up to approximately 49 ft at the top. Four domes of equal height are arranged within the production; a fifth, higher dome is in the showroom with a flat roof and visitors' center.
The five domes have dimensions of 89 ft x 89 ft in the floor plan. Single-curved, on the top and bottom segmented and trimmed glulam beams are located, which are connected to the welded box sections. Due to the high loading, box sections made of steel were used also for the valleys between the domes. They are cladded with timber panels for optical reasons.
Altogether, 1,800 glulam beams were used in the roof. The entire structure is supported on a steel frame substructure provided by the customer, which is positioned on a concrete floor slab. The roof has an architectural basic grid of 10 ft x 10 ft. The beams are segmented accordingly and follow the inclination according to the position of the dome. In the extension of the domes, inclined and segmented glulam beams are arranged which are connected to the steel frame structure of the facade.

In this article, the adequacy of a 2x4 dimension lumber subject to combined bi-axial bending and axial compression is verified using RF-/TIMBER AWC add-on module. The beam-column properties and loading are based on example E1.8 of AWC Structural Wood Design Examples 2015/2018.

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 RF-/STEEL EC3, I get an error message saying that the node with a support does not exist in the set of members. What is the reason?
- Can I use RFEM to calculate a log house three-dimensionally?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Is it also possible to subsequently deactivate the symbols for the FE mesh refinement in an existing graphic in a printout report?
- What is the difference between SHAPE‑THIN 9 and SHAPE‑THIN 8?
- SHAPE‑THIN calculates a very small shear area. Why?
- I would like to carry out the flexural buckling design for timber components with imperfections and internal forces according to the second-order analysis. Is it sufficient to activate this in Details of the RF‑/TIMBER Pro add-on module or is it necessary to make additional settings?
- Can I design laminated veneer lumber with RFEM/RSTAB?
- When calculating a connection using the FRAME‑JOINT Pro add-on module, a message appears saying that the value is out of the valid range (existing value: 108, minimum value 100, maximum value 100). What does this message mean?
- I have a trapezoidal roof structure supported by beams. However, the moments on the beams are smaller than they should be. What could be the reason for this?
