Wind Application with a fabric.
Wind Application with a fabric.
(OP)
Dear Group,
I have what I consider an unique structural problem. It basically involves two steel rods that are attached to a wall in the hortizontal, one on top of each other (approximately 50 " apart and the rods are 37" wide. The two rods are attached at each end in a bracket that allows rotation. The steel rods are connected by a fabric. The fabric is stretch by rotating the top rod with a ratchet to tigthten fabric like a drum. I have been trying to size the rod since I need to consider all the forces on the rod. This fabric is subjected to wind and is solid.

Any help would be greatly appreciated in determining the forces and how they would be acted upon the steel rod.
Thanks.

It is hard to explain, but that is it in a nutshell.
Thanks

If you assumed that the fabric was just a slab spanning onto beams it would give you a basic load & moment giving, say, a 1.5" tube or bar. Look at the stress & deflection & take a view. Problems like these are half calculation to see if you are in the right order & half judgement on top of that.
