if wood columns are supporting the existing beam you could install cleats under the new plies with through bolts couldn't you tony?

Yes, perhaps like a pair of steel angles on opposite sides of each post.

I sometimes use preservative treated wood and run it down the column to the concrete under additional plies, this provides the code required support under the new plies. in my ocean (salt water) environment galvanized steel don't last, and usually they don't want to pay for stainless steel.

a cleat is something that supports the additional plies that you'd add to the existing beam. it may be wood, could be steel angles. they go on each side of your column (if wood) and get bolted together. you could add a wooden member from the bottom of the beam to your foundation for the column. of course it goes without saying all wood used shall be preservative treated or of a naturally weather durable species. metal should be at minimum galvanized or coated, some preservatives used to treat wood are corrosive to metals.

ok cool, i was also thinking of adding another 4x4 post so that this main beam is (2)2x6 with posts every 4 feet,

but whats the best way to do that, is it possible to digg a hole and fill with cement and just smash in a 4x4 or what would the best way be

well I guess you could, but I CERTAINLY WOULD NOT .... go back and read post #42 again about footing. best to use a standoff post base connector to attach the column to the footing. How high is the deck off the ground (don't remember and don't have time to go back and re-read all the posts)?

yeah yeah that is what i mean dig a hole somehow under this beam and fill it with cement and the put in the steel post base thing then put the 4x4 in the base and tap it in.

cause doesn't the post have to be super tight again the beam.

it's only likw 15 inchs from the ground.

you could do that, or you could add properly size members to create a beam that would carry the load based upon the 8' span, either way works .....

ok i'm going with adding 4x4 posts cause that seems easier, other then digging the holes under the beam that is already there.

ok so i got footings dug and poured, and i found these cool brackets that allow you to tighten them once the support is in.

now the question of deck screws or nails, i've heard nails are better for the structure cause they can bend but i thought i woul ask you guys.

if you say nails what siz do i get?
