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. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
A "beam panel" provides you with the following advantages:
- Single-sided and double-sided sheathing is possible
- Automatic calculation of a semi-rigid coupling
- Boarded sheathing
- Stapled sheathing
- User-defined sheathing
- Representation as a complete geometric 3D object (frame, crosstie, column, sheeting, staples), including eccentricity
- Considering openings via surface cells
- Design of the structural elements utilizing the Timber Design add-on
- Independent of material (for example, drywall with cold-formed sections and gypsum fibreboards as the sheathing)

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.

Would you like to calculate curved beams (for example, made of glued-laminated timber)? For this purpose, you can use various section distributions for members:
- Curved
- Pitched cambered beam with constant height
- Pitched cambered beam with variable height
- Fish beam | Parabolic
