I am planning to build a corner pergola over my deck. Pergola is 8ft long from the corner on either side forming a triangle on the top. I have used four 4x4 posts (8 ft) attached to the deck headers using three 1/2" carriage bolt per post. How do I reduce wobbling when shear force is applied to simulate wind condition?
Since I am new to the forum, I am unable to post a picture. Imagine it's triangle with two beams parallel to the side of the deck forming a 90 degree angle and the third beam joins these two beams to form a triangle. Third beam has no supporting post. On top of the triangular beam, I have notched joists.
