CanopyMarqui Luxury Camping Tent, USA
Customer Project
Under Canvas began in 2009 with the opening of an all-inclusive glamping adventure package. It has since grown to include eight luxury glamping resorts and a customized event offering, bringing the glamping experience to life everywhere in the country.

Model
The Under Canvas safari-inspired tents include overnight amenities. Happy, well-rested glampers wake to the sounds of nature, perfectly positioned to explore America’s most iconic national parks and monuments.
Under Canvas operates locations in Yellowstone and Glacier (Montana), Moab and Zion (Utah), Mount Rushmore (South Dakota), the Great Smoky Mountains (Tennessee), and the Grand Canyon and Tucson (Arizona).
Structure
The CanopyMarquiTM tent is a nonagonal pyramid with a fabric membrane canvas spanning between each corner pole. The tent’s overall height is 21 ft, with an approximate base radius of 30 ft. The tent frame weighs 750 lbs, and the fabric cover weighs around 150 lbs.
CanopyMarquisTM can be conjoined into larger gathering spaces capable of accommodating hundreds of guests while feeling spacious and connected to the surrounding landscape. The awning sides of the tent are adjustable and can be put up or down to fit the weather conditions, or used as access openings.
The unique shape and flexible features of the CanopyMarquisTM tent create design challenges, particularly with deriving the wind load conditions. Standard codes, such as ASCE 7, do not cover the design wind pressure for unusually-shaped structures. The tent design wind loads were generated using RWIND Simulation, Dlubal Software’s wind tunnel simulation software.
Additionally, RFEM and RF-FORM FINDING were utilized for further structural analysis and design, including determining the shape of the tensile fabric under applied prestress forces. RF-TIMBER AWC was used to design the tent wood structures according to American standards.

Generation of Snow Loads in RFEM 6 According to ASCE/SEI 7-16 and EN 1991-1-3
The effects due to snow load are described in the American standard ASCE/SEI 7-16 and in Eurocode 1, Parts 1 through 3. These standards are implemented in the new RFEM 6 program and the Snow Load Wizard, which serves to facilitate the application of snow loads. In addition to this, the most recent generation of the program allows the construction site to be specified on a digital map, thus allowing the snow load zone to be imported automatically. These data are, in turn, used by the Load Wizard to simulate the effects due to the snow load.
New
Compared to the RF‑/TIMBER Pro add-on module (RFEM 5 / RSTAB 8), the following new features have been added to the Timber Design add-on for RFEM 6 / RSTAB 9:
- In addition to Eurocode 5, other international standards are integrated (SIA 265, ANSI/AWC NDS, CSA 086, GB 50005)
- Design of compression perpendicular to grain (support pressure)
- Implementation of eigenvalue solver for determining the critical moment for lateral-torsional buckling (EC 5 only)
- Definition of different effective lengths for design at normal temperature and fire resistance design
- Evaluation of stresses via unit stresses (FEA)
- Optimized stability analyses for tapered members
- Unification of the materials for all national annexes (only one "EN" standard is now available in the material library for a better overview)
- Display of cross-section weakenings directly in the rendering
- Output of the used design check formulas (including a reference to the used equation from the standard)
- How can I neglect torsion in the steel and timber design?
- How do I perform stability analysis to determine the critical load factor in RFEM 6?
- Why do the results in a modal analysis differ between the initial prestress and the surface load?
- Where can I find the materials for the corresponding National Annexes in RFEM 6 and RSTAB 9?
- How do I apply wind load on members of open structures?
- Although I have modeled two identical structural systems, I obtain a different shape. Why?
- How does the "Orthotropic Plastic" material model work in RFEM?
- What is the meaning of the superposition according to the CQC rule in a dynamic analysis??
- How is it possible to make factorized combinations of a dead load in the context of form‑finding?
- My aim is to mesh a circular hole plate in a mapped way. Is such a meshing possible in RFEM?
