The project's architectural as well as structural highlight is the huge timber roof rolling across an area of 645,835 ft², spanning the building like a giant wave, that was designed by the Austrian company Graf‑Holztechnik.
The primary structure, consisting of mighty glulam beams, rests on steel and reinforced concrete columns up to 66 ft high.
The structure supports a record amount of approximately 282,517.3 ft³ of cross‑laminated timber slabs. The three- and five-layer panels have a thickness of ~ 4.7 to 9.5 inches and a span length of up to ~ 32.8 ft. The thickness was calculated for each slab in order to dimension the structure to be as slender and economical as possible.

In this article, the calculation of a timber panel wall with the beam panel thickness type is compared with a manual calculation.
Using the Timber Design add-on, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling strength calculated by the Timber Design add-on using step-by-step analytical equations as per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
When calculating regular structures, data input is often not complicated but time-consuming. Input automation can save valuable time. The task described in the present article is to consider the stories of a house as single construction stages. Data is entered using a C# program so that the user does not have to enter the elements of the individual floors manually.
Our webservice offers users the opportunity to communicate with RFEM 6 and RSTAB 9 using various programming languages. Dlubal's high-level functions (HLFs) allow you to expand and simplify the WebService's functionality. In line with RFEM 6 and RSTAB 9, using our WebService makes the engineer's work easier and faster. Check it out now! This tutorial shows you how to use the C# library by means of a simple example.
In RFEM, the oriented strand board (OSB) material is available for the USA and Canada. The material parameters are taken from the "Panel Design Specification manual".
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. Simply specify the surface geometry and the timber panel elements are automatically generated using an internal member-surface construct, including the element connection stiffness. The Beam Panel thickness type is defined using the Multilayer Surfaces add-on.
A "beam panel" provides you with the following advantages:
- Single-sided or double-sided sheathing
- Automatic calculation of a semi-rigid coupling between studs and sheathing
- Nailed sheathing connection
- Stapled sheathing connection
- User-defined sheathing connection
- Representation as a complete geometric 3D object (frame, studs, surface, etc.), including eccentricity and automatically calculated stiffness between elements
- Consider openings via surface cells
- Design of the individual structural elements utilizing the Timber Design add-on (full shear wall design planned for a future release)
- Other material options available (e.g., particle board, gypsum, or fiberboard sheathing with cold-formed steel sections)
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
- Binderholz (USA)
- KLH (USA, CAN)
- Kalesnikoff (USA, CAN)
- Nordic Structures (USA, CAN)
- Mercer Mass Timber
- SmartLam
- Sterling Structural
- Superstructures listed in Lignatec Edition 32 "Cross-Laminated Timber of Swiss Production"
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
How can the NDS and CSA O86 factors be manually adjusted for consideration in the Timber Design add-on?
What calculation is carried out for the NDS Strength Configuration "Calculation of Torsion" options?
Which Dlubal software products do you recommend for the structural analysis and design of timber structures in particular?
How can I model a timber beam with stiffening on both sides? (splice)
How can I generate an area load on members via cells in RFEM 6 or RSTAB 9?
Which programs do I need for laminate and sandwich structures, or cross-laminated timber (CLT)?
