Decks are home extensions that can be elaborate and fancy or plain and simple. Homeowners build these extensions to increase the value of their homes. However, how much do decks weigh? We inquired from experts, and they gave us exact calculations.
Calculating the weight of a deck will depend on the type of timber or lumber and fasteners used in construction. A 10' by 10' deck made of southern yellow pine will weigh 950 pounds. Therefore, the estimated weight is 9.5 pounds per square foot.
You will need some basic math to do any calculations concerning your deck. Continue reading as we walk you through the dos and don'ts on deck weight.
Calculating The Weight Of A Deck
Decks can be free-standing or attached to your home. Free-standing decks are easy DIY projects, and the end product could be movable.
To calculate its weight, you'll need to consider some factors. The type of lumber or timber and fasteners used will add to the overall weight of the deck.
Different types of lumber weigh differently due to water density. For instance, southern yellow pine is heavier than white fir in water density.
Calculating The Weight Load Of A Deck
All decks should be primarily engineered to carry their weight and any additional weight. The load is calculated in pounds per square foot (PSF).
However, some calculations are in pounds per cubic foot. The weight per square foot will vary due to different soils and their bearing capacity.
The weight or load is in two sections:
The deadweight is the deck's weight. It's stationary! Therefore, it's referred to as dead weight. It could be 10 pounds per square foot.
Additionally, you have the live weight. The live weight consists of people, deck furniture, and other furnishings. It can total around 40 pounds per square foot.
Both live and deadweight give you a total weight of 50 pounds per square foot of the deck. Depending on the type of material used for construction, some decks can carry up to 100 pounds per square foot.
Ensure that you build your deck following deck building codes and requirements for residential buildings.
Deck Weight Redistribution
Your deck is an extension added to the house. Its weight is redistributed to the house and the footings. The footings in turn push the weight into the ground. The wider the deck footings are, the more resistance they will have.
Additionally, the type of soil in your locality will also contribute to a stable or wobbly deck. If you need footing for your deck, ensure you calculate the footings accurately.
Miscalculation of the deck weight redistribution could rip the house as it sinks into the ground like in quicksand.
How Much Weight Does A 10 by 10 Deck Carry?
When constructing a deck that is 55 pounds per square foot, you should multiply this with the area of the deck. A 10x10 will give you 100 square feet of deck area. Then multiply 100 by 55 equals 5,500 pounds. Therefore, the total weight the deck can carry is 5,500 pounds.
How To Determine The Footings
Typically, you get the area a footing holds by multiplying half the width by half the length of the deck. Next, take the footing area and multiply by the pounds per square foot.
For example, 25 square feet multiply by 55 pounds per square foot equals 1,375 pounds. To calculate the area of each footing needed, you'll divide 1,375 pounds by 13.88 pounds per inch of soil compression. The footing area should be 99.06 inches
Footings are usually round, and the right diameter is important. You might want to invite a professional to help build the deck if you want a complicated design.
