This is pretty much what it looks like. The values don't need to be perfectly precise. They serve only as a "minimum requirement" for the strength of the walls/tarp. I did have a structural engineer type this problem into one of his fancy computer tools but I would really like a formula to...

Don't we divide by the wall thickness in this formula? If we assume a wall thickness of 0 then we can't use this formula. or am I misunderstanding something? Edit: would I just not divide by the thickness and then multiply by the length to get the total Force f for the whole length?

In the corners, they certainly would but the further you get from them the less they support the tarp and the more of the force has to be absorbed by the main(longer) walls. If the walls will have to sustain this force in the center anyway, it's not a problem to (wrongly)assume they will have to...

How would I calculate the hoop stress if I assume the tarp does not have any thickness?

The tarp is attached to the walls and is sagging down between them due to the pressure. Technically the tarp is stretched over the top of a "box". but the box is significantly longer than it is wide and I only want to know the force for a section in the middle so the shorter walls can be...

Thank you for the answer. I had falsely assumed the tarp would have a parabolic shape which caused my calculations to be off. the tarp having a circular ark makes a lot more sense. I need to know the force since I need to know how strong the walls and the tarp have to be. the whole construction...

Hi. I have a problem I'm trying to solve. I have a tarp that is stretched horizontally across two walls. The walls are 5.5m apart and 50m long. There is a pressure of 10mBar above the tarp pushing it down, making it sag about 0.15m in the center. I'm trying to calculate the force with which the...
