Crowing
Years ago we had a cattle panel hoop house for the donkeys and sheep, like the one pictured in NagemTX post, but with wood frame at each end and two metal fence posts. It survived 80 mph wind. In 100 mph wind one of the panels bent a little, but survived more years. The curve, facing the wind, is aerodynamic. The air goes around the structure.
At the same time, we had chickens in a small wooden coop, looking similar to an outhouse, again with two metal fence posts to secure it. This structure also survived. The greenhouse did not.
