In summary, you would need a lot more information to create a model of how the material will behave, and how much tension you can apply to the straps.

hello! first time poster here. i am looking for advice in the construction of a suspended triangle shaped platform, made priciply of a web of seatbelts under a layer of ripstop, all sown together. using trees or rocks to anchor the corners of the triangle. (this type of tent has been done on a smaller scale sucsessfully under the name "tenstile", using rathcets to tighten the line) is there any way to model the slack and potential stretch of the material? or even just to see at what weigh the web will start to sag. my thoughts are that with a six inch ratchet and 6 in seatbelt material line the structure will be taunt enough to hold three full adults. i have uploaded a pic for visual referance of the webb pattern, the triangle is 26 feet on each side.

I think we'd need a little more info on a few things, like how much sag is acceptable (you'll always have some), and how much pull you can get on the 6" ratchet strap. How much sag you get in the middle of it will also depend on if you put a preload on the internal web segments, thus increasing the tension on them...

I don't have the tools or know-how to analyze something like that, if the weight of the 3 people is 500 lbs, and you put them in the center, and let say you have a 5000 lb pull on the strap (I think that's well within the working range of a 4" truck tiedown strap), and draw the vector diagram, you'd get at least the minimum sag (perhaps not the maximum though).

Do you have anchor points that are really capable of holding even close to what a 6" strap can pull?

Someone more knowledgeable than me is going to have to take it from here

FAQ: Design\modeling advice for unorthodox structuretructure

What is unorthodox structuretructure?

Unorthodox structure refers to a structure or design that deviates from traditional or conventional methods. It may involve unique or unconventional materials, shapes, or methods of construction.

Why is design and modeling advice important for unorthodox structuretructure?

Design and modeling advice is important for unorthodox structure because it helps ensure the safety, stability, and functionality of the structure. Since unorthodox structures may not have been tested or used before, it is important to thoroughly plan and model the design to identify any potential issues or flaws.

What factors should be considered when designing an unorthodox structuretructure?

When designing an unorthodox structure, factors such as the purpose of the structure, the intended use, the location and environment, the materials and construction methods, and the potential risks and safety measures should all be carefully considered.

How can modeling help in the design of unorthodox structuretructure?

Modeling can help in the design of unorthodox structure by providing a visual representation of the structure and its components. It can also simulate different scenarios and test the structure's stability and performance under various conditions, helping to identify any potential issues and make necessary adjustments before construction.

What are some common challenges when designing and modeling unorthodox structuretructure?

Some common challenges when designing and modeling unorthodox structure include limited data and information on similar structures, lack of standardized design codes and regulations, and potential difficulties in obtaining necessary permits and approvals. Additionally, the complexity and uniqueness of unorthodox structures may require more advanced modeling techniques and tools.
