Planning a hoop house, or cold frame style greenhouse. I live in Nebraska, we get pretty consistent winds, not unusual to have 50 mph gusts.
I want set two parallel 3-4 ft tall rows of 4x4 posts, 4 ft apart. The 1-3/8" diameter "hoop" arches (made from chain link top-rail) will get secured to these posts every 4 feet.
I really don't want to bury the pressure treated 4x4's in: A) the heavy clay we have here B) concrete
When they rot out, it would be difficult to replace if anchored by a 500 lb block of concrete.
Can I use a sonotube, then wet-set a 4x4 saddle and attach 4x4 to the saddle?
I read that concrete saddle's aren't really designed for wind-sheer (fencing) loads. Not sure if my hoop house would apply more of a wind sheer or downward force?
