On the first cold night, the winds caused the sides to widen and the center to collapse. I put it back together using more clips and big bricks on the ground connections to prevent ground level spreading. The next cold windy night collapsed the structure again. Both times I was so intent on fixing the problem, I forgot to photograph the collapse. With my daughter’s help, I calculated the upright lengths needed to conform to a 90-degree top connection. My uprights were cut from 9.5 feet to 7.07 feet. The height of the structure was reduced from 8 feet high to 5 feet high. You can see the bricks used to brace the frame.
