Pavilion Corner Brackets

Trying to build a 16x14 pavilion with no corner knee braces. I know it can be done as a large pavilion manufacturer makes them this size without the need for knee braces. I'm using 6x6 post with a tripple 2x10 beam(manufacturer only uses a double 2x8). I bought these 1/8 steel corner brackets that I though would enough to attach post to beam connection (beam just sits on top of post, not notched in). The 2x10's are a staggered joint where they lay on top of the 6x6 post. I used 3"x1/2" lag bolts to attach the corner bracket.

After I got everything all tightened up I get a noticeable wobble if I push on the upper part of the post. I can get it to wobble by pushing hard and back and forth. I would expect no wobble if braced/bracketed correctly.

I'm pretty sure I need more bracing/brackets to stop the wobble, but I can't find any specialty brackets for the inside of the post/beam like the one I have on the outside. I believe I just need a solid brace that goes from the underside of the beam and attaches to the 6x6 post. Is just a common (really thick) "L" bracket with lag bolts suffice, putting two "L" brackets per post(where the beam intersects the post). Doesn't have to be pretty as I'm wrapping all wood with PVC board.

I've attached a picture of the current and only bracket I have on the pavilion.

 

How are the bottom ends of the posts attached?

 

Why in the world am I seeing OSB underneath the bracket?

 

You mention a manufactured unit but have you pushed on theirs at the same point in construction?

 

Hello. I’m currently in the same situation as you ran into. Any luck on finding options to secure the beams on the posts? Did you use pressure treated 6x6’s? Did they twist at all? I’m trying to locate 6x6 cedar with no luck other than special order.
