I have a similar but what seems like a more complicated problem.
I built a completely freestanding elevated platform (9ft up)for my kids playset (12x18) to be built off of. It rests on (6) 6x6 posts sitting on 10" diameter concrete piers, with doubled up 2x10s acting as beams between each pair of posts.
After assembling the posts, beams and joists the platform had a serious sway on top, despite being very stable vertically. I added several diaganol braces from the joists to the beams and posts. This helped with some of the swaying, especially parallel to the beams. The swaying perpendicular to the beams was much worse.
I am considering diagnol bracing from the beam to the base of the posts OR heavy gauge cable bolted to each side with a tensioning turnbuckle on each cable.
Any thoughts on the two bracing methods??? or how to attach them most securely to the beam and posts?
Please note that I intend to hand a climbing wall, swings, a slide and other playset items off of this platform.
Thanks for your insight!
The bracing needs to be rigid on both sides of the post. I know you want to minimize the visual under the deck, but I don't think you can avoid the 2x4 bracing.

Can we put some punctuation in there somewhere, anywhere?
There are commas and periods out of work.

Deck swaying too much...help needed


Bump.
I plan on installing the sway bracing this weekend and wanted to follow up with a couple questions.

Do you think I could make upside down Vs between the posts (top to bottom) instead of using 1 diagonal between the posts? The upside down Vs would still allow easier access to t.e underside of the deck. Or is the roughly 45 degree angle with the one diagonal make a bigger difference?

ALso, tonight I clamped a couple 2x4s between 2 of the posts and shook the deck...couldn't discern any noticeable difference in the amount of sway. I'm sure part of this is because the bracing was only clamped and not nailed. Is it worth it to try to nail these shorter pieces at every post or will I ultimately be disappointed? I'm more concerned with safety than appearance and functionality but would like the best of both worlds if possible. Who wouldnt?

Thanks again for all the advice!

If you want to brace the deck but not see the bracing, you could attach 5/4 to the bottom of the deck diagonally. Serves the same purpose as installing the deck at a diagonal and is nearly invisible.

Yes you did. I didn't steal it, I just missed it. Maybe your sarcasm had something to do with the criticism.

Where I live (earthquake country), none of these suggestions would pass inspection by themselves. Way more bracing required.

A poor pic representing the bracing, but you get the idea.
