How much weight can a 6x6 beam hold horizontally?
A 6x6 with 12' span can support 2000 lbs. if you assume a conservative 1400psi bending stress. If you do a good job bonding the two members together, your double 6x6 can support more than 4,000 lbs.
Can a 6x6 be used as a deck beam?
First, the IRC only allows certain dimensional lumber to be used for deck beams. In the past, 4x4s and 6×6 lumber could serve as beams, that is no longer the case. You must use 2x material bolted together to create a deck beam, or use metal or engineered lumber.
How much weight can a 4x6 beam support?
2 and better (no loose or missing knotholes), then a 4x6 spanning 18' will support about 105 lbs. loaded at the mid-span (slightly higher if it's loaded at third points or further from the center point).
How big of a beam do I need to span 16 feet?
For a 16 foot span, you will need atleast 3-2×14 or 6×14 size of wood beam. Thus, a 3 nailed 2×14 or 3-2×14 or 6×14 wood beam can allow to span 16 feet. For a 16-foot spans, the wood beam has to be at least 14 inches in depth and 6″ in width (3-2×14) used for residential building, wood frame structure or projects.
How far apart should 6x6 posts be?
8 feetFor Building a Deck Railing, Deck Frame, or Fence The maximum spacing of 4x4 deck posts should be 6 feet on center, while the maximum spacing of 6x6 deck posts should be 8 feet on center.
How do you calculate wood beam load capacity?
Calculate the maximum bending moment for the wooden beams. The bending moment is the length of the span times the weight to be supported divided by 8. For a beam spanning a 12-foot room and supporting a weight of 600 lbs., the maximum bending moment would be 12 x 600/8 = 900 foot-pounds.
How far can a 4x4 beam span without support?
The initial sag or deflection will typically increase by as much as 50% over time, even with nothing other than gravity affecting it. By itself, with no load, a 4×4 will span 8 feet without noticeable sag.
How far can a beam span without support?
Some manufacturers limit their beams to 60' due to transportation issues, while others have the capability to manufacture beams up to 80' long. So, the longest unsupported span possible using LVL would be 80-feet. Typically, though, it is common for a continuous LVL span to be between 20' and 30'.

Can a 4x6 be used as a beam?
Second Step: Obviously, the larger the beam, the greater the distance it can span between posts. A Redwood 4x6 beam should span no more than 6' between supporting posts.
Can you build a deck without a beam?
Beams are a crucial part of any deck, so it's imperative that they're properly installed. A beam runs across the posts, parallel to the ledger, and supports the joists.
