Web in axial compression, wood is typically good for at least 1200 pounds per square inch, so a 6x6 true dimension post would have an area of 36 square inches, and would be good for about 40,000 pounds in pure axial compression. This is more than enough weight capacity for most normal applications such as a fence or supporting a deck. How do i determine the maximum load capacity of a 6x6 lumber post? Does that seem to high? The pine is roughly have the cost of the other two of course.
P = the allowable column axial compression load. Web i built a playhouse for my kids using four 4x6 posts to support the house. Sponsored links related topics beams and columns Web loads must be concentrically distributed evenly over the top of the column shaft. P = fc * cp * a.
Swings can expose a lot of sideways force and so the posts need more support than you have described. Web this post base is available in model sizes for double 2x, 4x4, 4x6 and 6x6 lumber, both nominal and rough. However, if the post is a stronger grade, the strength goes up quite dramatically.

The pine is roughly have the cost of the other two of course. However, the post will typically buckle under much lower load than the axial compression. Does that seem to high? Uniformly loaded beam overhanging post calculator: How can i determine the compression and/or vertical weight that a 6 foot 4x6 can support? Web i built a playhouse for my kids using four 4x6 posts to support the house. However, if the post is a stronger grade, the strength goes up quite dramatically. Fc = allowable compression parallel to grain. I do see a problem with just using a single post for the verticals on each end. The allowable column compression is determined by the formula. The snow load is treated as a live load when you use awc’s tables. Web this post base is available in model sizes for double 2x, 4x4, 4x6 and 6x6 lumber, both nominal and rough. I have a small front porch with only the roof above it. Web the pair of 6x6 timbers spanning the twelve foot distance should be plenty strong to hold up the swings and swingers. Capacities are per post/column and allow for a safety factor of 5.

Each one will be buried 4' deep and concrete poured into hole to support. A = area of column cross section. You may have to work the problem from each. 4,500/4 = 1,125 lbs per 6x6 post?
Capacities Are Per Post/Column And Allow For A Safety Factor Of 5.
6 x 6 will be supported every 5 ft on a concrete pier. Web the vertical load capacity of a plain wooden post will depend on its height. While the 6×6 post has a higher load capacity, the 8×8 post offers a more. The pine is roughly have the cost of the other two of course.
This Information Is Found In The Code Book.
However, the post will typically buckle under much lower load than the axial compression. 1 the 6x6 and the double 2x12 are sufficient in themselves for your swing. Web the only thing it notes for a post is that they must support 2,500 lbs at each end. Web can i replace a wooden porch post with a 4x4x.25 aluminum box tube?
