Under Canvas safari-inspired tents look to reduce environmental impact while still delivering a luxurious camping experience. Operating in many beautiful and well-known national parks and monuments throughout the USA, these safari-inspired tents give campers the ability to sleep soundly, ready to explore nature by morning.


The Four-Season-Arch is a beautiful centerpiece tent for luxury camping resorts. It has a unique esthetic shape. The tent may consist of one pod or multiple pods. Each pod has three equal sides. Each side is framed with a glulam timber arch, spanning about 26 ft,  with an arch rise of approximately 10 ft, positioned at a slight tilt. The three side arches are held together with horizontal timber beams. Round posts, each measuring around 24 ft long, are placed at the center of the horizontal timber beams, forming the pointed tipi tent appearance at the center pod. Two 10-foot awning poles are positioned at the entry doors.

Heavy-duty membrane fabric covers the pod framing and forms the conical-dome tent shape. The tent access opening can be opened or closed with fabric as well. RFEM and the RF-FORM FINDING add-on module were used in the structural analysis and design of the structure, including determining the shape of the tensile fabric under applied prestress forces.

Determining the design wind load is challenging for the Four-Season-Arch's unusual structure shape. The only way to produce an accurate wind load for this tent is either to use actual wind tunnel testing or wind tunnel simulation software. RWIND Simulation by Dlubal Software was the program chosen to perform the wind analysis on the tent structure. RF-TIMBER AWC was used to design the tent wood structures according to American standards.
