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 aesthetic 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 chosen program to perform the wind analysis on the tent structure. RF-TIMBER AWC was used to design the tent wood structures according to American standards.

The Aluminum Design Manual (ADM) 2020 was released in February 2020. The ADM 2020 gives guidance for both the allowable strength design (ASD) and load and resistance factor design (LRFD) for aluminum members to ensure reliability and safety for all aluminum structures.

With the activated option "Topology on form-finding shape" in the Project Navigator - Display, the model display is optimized based on the form-finding geometry. For example, the loads are displayed in relation to the deformed system.
- SHAPE‑THIN calculates a very small shear area. Why?
My member is oriented at the inclination of principal axis when I import from SHAPE-THIN to a 2D RFEM model. How do I fix this?
- It seems that the members stay not deformed after my RF-FORM-FINDING calculation. What did I wrong?
Can I export my cutting pattern?
- How do I model a tent roof with two cone tips?
- How do I model a suspended membrane roof structure with line supports?
- How can I get the member end forces to design the connections?
- I would like to calculate and design "temporary structures." What do I need for this?
- How is an inflatable object simulated in RFEM?
- I have already divided my membrane roof into individual surfaces. Can I quickly create a cutting pattern from these surfaces?
