I'm building a rather large outdoor shelter/square gazebo. I'm using 6x6 Juniper posts anchored to cement columns using Simpson post ties. The 4 posts are in and have a concerning wobble. Before I put 6x8 beams up, what can I do to to strengthen these posts? Would heavy duty angle brackets do the trick?

Once the top plate and roof is on it will lock everything together.

U can put temporary braces to ground or add angle brace from post to plate. If done right it would add to design.
