How much weight can a 12x12 deck hold?

A 12'x12′ (144sq') deck properly supported can hold 5 760lbs on it. you build. All floating decks, in fact, all decks built to code, can support no less than 40 lbs per square foot of deck.

Can a deck hold 5000 lbs?

To find out the maximum weight your deck can hold, you'll need to multiply the total area by 50 psf. For example, a 100 square foot deck can support 5000 pounds. Again, this is an estimate that engineers have decided is a safe value for a deck accounting for the typical items a deck would hold.

How much weight can a deck withstand?

In general, most decks can withstand 100 lbs per square foot.

How much weight will a 10x10 deck hold?

In short there's no one right answer to “how much can my deck hold?” However, one rule of thumb to keep in mind while answering the question is that the answer commonly is that if a deck is properly designed, it's built to hold 50 lbs. per square foot.

How much weight can an average wooden deck hold?

In both theory and practice, most decks built with traditional wood framing are designed to carry loads of about 50 pounds per square foot (PSF).

Can a Hot Tub Go on a Wooden Deck?



Can I put a small pool on my deck?

Decks that are lower to the ground pose less risk of injury when collapsing, but can be just as costly to repair. Smaller inflatable pools that fill up less than a foot of water, may be fine to put on a deck, but there are still risks involved.

Can a wood deck support a hot tub?

Yes, you can put a hot tub on a deck. Decks built ground level up to 2 feet off the ground can support up to 100 lbs per square foot; sufficient for most hot tubs.

Can my deck support a gazebo?

Yes, you can put up a gazebo on your deck, and this applies to both fixed and pop-up structures. A deck makes an attractive floor for your gazebo, and with a bit of planning, you can secure it without messing up your boards. Using your existing deck saves you the cost and effort of installing a floor for your gazebo.

How much weight can a 2x10 deck hold?

If you find that your deck joists are 2×10, but the deck load calculator only mandates 2×8 joists, then you can safely assume your deck is much stronger than 50 pounds per square foot.

What is deck dead load?

Dead Load consists of the weight of the deck structure that sits on top of the posts. An average deck would be designed to handle a load of 50 psf (pounds/square foot) and is made up of 10 psf for the dead load and 40 psf for the live load.

Can I put a pool on a wooden deck?

Building a deck to hold a pool takes a little extra planning. You can place a pool on a wooden deck if the construction takes into account several factors. Of course, pools are very heavy. And a lot of water will be splashed, poured and dripped on your wooded deck, potentially weakening it over time.

How do you calculate weight capacity?

Subtract the curb weight from the GVWR to find the payload capacity. For example, if you have a light-duty truck with a GVWR of 9,000 pounds and a curb weight of 6,000 pounds, the payload capacity will be 3,000 pounds: GVWR – curb weight = payload capacity.

How do you reinforce a deck?

To stiffen the deck, go underneath and install a row of 2x8 blocks down the center, perpendicular to the joists. Stagger them with enough room to nail or screw them in place through the end grain, then fasten the treated 2x4s to the underside of the joists so they run from corner to corner, forming an X.

Do I need to reinforce my deck for a hot tub?

Keep in mind that when designing a new deck with a hot tub on top, you'll only need to add extra reinforcement to the area right below the hot tub. So instead of overbuilding the entire deck to account for the added weight of the hot tub, you build a deck to standard code and reinforce the area beneath the hot tub.

How do you calculate load bearing capacity of wood?

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.

Can I put a free standing pergola on a deck?

Pergolas can extend from the wall of your house or can be freestanding anywhere along your deck or in your yard.

Can I build a pergola over my deck?

You can build a pergola on an existing deck, though you will need to cut away some of the deck boards to attach the posts to the deck structure. Although you could fix the posts to the deck boards with post bases rather than to the structure below, it won't be as reliably strong.

Can I build a pergola on an existing deck?

You can install a pergola on a low elevated deck as long as it has stable supports. For the best support, the banisters of your deck can support the pergola. They should run two to three feet into the ground and be set in concrete. In cold climates, dig three to four feet deep for additional support.

How do I know if my deck is strong enough to hold a hot tub?

As a general rule of thumb, if you have a deck that's raised only a couple feet or less, it can support about 100 pounds per square foot. So, if the spa is less than 100 pounds per square foot you likely have nothing to worry about.

Will a deck hold a portable hot tub?

Yes, any kind of hot tub, including inflatable hot tubs, can go on a wooden deck. However, if the deck is more than 2 feet off the ground, it will likely need additional support to hold the weight. Even inflatable hot tubs can still weigh up to 3,700 lbs full of water and people.

Can decking hold the weight of a pool?

Common decks typically have a design load of about 50 pounds per square foot. This pool would put a deck well over its weight limit. Although decks can be designed to carry such a load, most aren't.

Can a deck hold a pool table?

Where Can an Outdoor Pool Table Be Placed? An outdoor pool table can be set on any surface. However, we recommend pavers, a concrete slab or deck for best results.

How big of a pool can you put on a deck?

Safety codes stipulate that a deck should only hold 40 lbs. per square foot. Most children's pools hold much more than one cubic foot, but even one foot is in violation of this number, which does not include the weight of children in the pool or adults monitoring the activity.

Is it normal for a deck to shake?

If your deck gets a case of the shakes when you walk across it, there's probably no reason for concern. Still, in some cases, the deck movement puts extra stress on the fasteners and connectors.
