Lateral load
Lateral load
(OP)
I have to design a wall to contain 24 feet high recycled paper bales. Each bale is 3 feet high. What would be the load these stacked bales will exert on wall
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: Lateral load
Well how about another idea:
Consider a wall of stacked cylinders. The cylinder above has a weight, W, which acts on the two cylinders below with a normal force, N, on each. These normal forces act at an angle 30 degrees away from straight up. These forces act toward each other to create horizontal equilibrium. The vertical component of each normal force is 0.5 x W. The horizontal force is 0.29 x W. This can be converted into a Ko value.
This logic assumes perfectly round, tightly packed particles. The bundles, are likely to be less prone to exerting horizontal forces than perfectly round particles, so long as they remain in bundles. Once the binding is removed, then we are considering the individual sheets sliding over each other. I don't know how to solve that problem, but I know Ko can never exceed 1.0.
Good Luck.

Maybe look up the barrier loads for carparks and adjust the details to suit.

RE: Lateral load
Most waste paper bales are very irregular and extremely unstable. If the bales are stacked 24' high that is 8 bales at 3' per bale. My experience (in a prior life)as a manager of a large integrated pulp & paper mill sez that you can be assured that these stacks will fall against the walls. Therefore, I would recommend that you install heavy timber "bumpers" on the side of the walls and design the walls for the impact of the bales falling from the top of the stacks or for a 24' high stack of bale to fall against the wall.
To get a better idea of what you are dealing with you might visit a waste paper recycling business in your area.
Good luck
