Since our shade structure is sorta permanent here in southern Utah and we are not allowed to have structures anchored to the ground we have a unique tent/cabana set that other than destroying canopies every 3 or 4 years has held up. We take a standard 10' x 10' easy up with straight upright legs and set the legs in 4' pieces of chain link fence woven in 1' tube, drill holes into the legs and wire them to the fencing and fill with 2" diameter rocks on all four corners. At the top where the expanding cross braces are bolted, bolts are removed and wood screw carriage bolts are screwed from the inside out into 2" x 4" x 10' lumber that surrounds the top the fabric is then attached to the lumber. Top supports are reinforced with bamboo that grows here wrapped with duct tape. By laying lumber on the ground, tarps can be made into walls and reinforced with bamboo running vertical between the top and bottom lumber held on with 2" staples. It is the only way to beat the wind here. Attach outdoor carpet to lumber on the ground and set heavy items next to the walls if it gets really bad and don't get the vent at top of canopy as it will quickly go away!
