Above Ground Pool Wall Failure
Does anyone know of any good reference material on pool failures? I've been searching teh internet with little luck. I'm inspecting a couple of pools for an insurance company. They're both above ground, round pools, approximately 24' in diameter. The homeowners are clamiing that the pools failed due to the weight of ice/snow (a covered loss) vs. normal aging (which isn't covered).
In both cases the rivets where two wall panels meet popped, opening the pool like a zipper. I didn't see any sign of corrosion. It seems to me that a few feet of snow/ice on top of the cover could overstress the tension tie, which was probably designed for only the weight of the water in the pool plus some factor of safety. The pools are both located in New Hampshire, which had a particularly tough winter this year (many roof collapses).
I'm interested in design information that would offer me some insight as to the design of the tension ties and what kind of weight on the cover they can normally hold. Any informatin on failures of this type would also be appreciated. Attached are photos of one of the pools.
