I am adding a 16' x 15' canopy to a patio consisting of two 7.5x16 panels of draped cloth suspended from steel cables, like the product you see here: https://www.infinitycanopy.com/
I would like to support the canopy from a steel post and beam system to match the existing design of the space. Like so: |¯|¯|, 10' vertical and 7.5' spacing between posts.
What I'm trying to determine is the lateral load on the top beams and the minimum size steel bar I can use.
The cables are hand tensioned and the panels weigh a total of 75lbs. The canopy will be retracted when not in use and won't be used in significant winds.
I know the safe bet would be to use 4x4" steel and bury 5' in concrete but I am hoping I can get away with something a little more delicate looking, 2x2 bars would be ideal from a design standpoint but 3x3 would be acceptable.
Anyways, is there a way to estimate the lateral load I need to account for?
Thanks in advance
