you can also buy code-approved metal brackets that allow you to connect wood deck beams to wooden posts. i have used these when they are specified by an architect or a homeowner. these brackets are easy to work with and will do a good job of making the connection.
when you find a deck built like this one, it makes sense to check every point where a connection should have been made. for the strongest connection of beam to post, place the support beam directly on top of the posts, rather than bolting them to the side, so the full load is transferred to the posts.
the beam you are working with often supports half or more of the weight of the deck, and anything that will eventually be on the deck. the floors joists, decking, furniture, and people rest on the beam and transfer the load to this beam along its entire length.
this post should actually do double duty as a stair post and an additional support post for a beam or ending floor joist that may run parallel with the front wall of your house. the post should be one continuous length of lumber that extends from the top of the railing to a special metal connector that is solidly anchored into a concrete pier at ground level.
wood may be the most common material to use but with these basic deck railing ideas you can spice up anything. allowing every second or third post to stick up above the top rail can be a very nice touch especially if you allow only corner posts to protrude. it tends to emphasize the corners and the shape of the deck.

confirm that the beams are securely fastened to the tops of the posts or piers. peer down the length of each beam to be sure its not sagging under the weight of the deck. if it is, youll need to shore it up by installing one or more supports. if the beams are made of untreated lumber, they must be at least 12 in. above the ground. 5.
if you have seen the deck joist span table, you already understand the relationship between joist span and joist spacing. the closer you space joists, the longer you can span joists up to a point. for determining beam spans distance a beam can span between supporting posts , consider the following concept.
notched wood post beam connection. most deck builders use a reciprocating saw to cut an l shaped seat in the top of the post large enough to hold the beam. another building method to consider if you dont have a reciprocating saw involves using circular saw to score the top of the post to remove the weakened sections with a chisel.
deck railing code. the railing must be strong enough to resist the following loads: 125 pound uniform load per linear foot applied horizontally or vertically to the railing 200 pound point load applied at the top of the post in any direction, or at any point along the railing.

recommended beam and joist spans for deck framing. the bigger you make your deck, the more you ask of the framing timbers that hold up the deck's structure, and the joists and beams that support the deck's floor can only span so far before the whole deck becomes a safety hazard. the dimensions of the framing, the type of wood the framing is made from,
continuous joists over a center beam give you the advantage of creating a stiffer floor. but with that arrangement, you may need to install a larger center beam or increase the number of support columns. the comparison depicted above assumes the same joist size e.g. 2x10s for each case.
railing systems. the posts should be a minimum 4×4 size and be solidly anchored to the deck joist and rim joist of the structure. use two through-bolts and a metal tension tie for the upper bolt connection. if a decks guard-posts anchoring does not have a minimum allowable tension load of 1,800 lbs. for a 36-in.
