calculating weight of a wood deck

What a great question. The issues around deck load capacity is one I receive often from visitors asking how much weight they should design their deck for. The discussion quickly leads to the overall strength of the framed structure. But that is only one part of it. That's because any analysis of what load a structure may bear

Is there a simple way to to check that the deck can withstand the weight? (MI) I see you are on the West Coast - any chance the wood on your deck is cedar or redwood?

Part 1: How to calculate footing loads and the weight of a deck. BY: BOB HEIDENREICH. If you're a deck builder, you know that numbers are a common occurrence throughout your day-today schedule. Because of this, you also know that there are fast formulas for estimating lengths and loads—and that's why knowing “deck

by only relatively small changes in weight per cubic foot, , owing to the counter effect of change in volume as a result of the accompanying shrinkage or swelling. A practical rule for estimating the weight of air- dry Or kiln-dry wood at a moisture content, in the neigh- borhood of 12 per cent, is to regard a # per cent change.

Deck height of 10 ft. Deck dimensions of 12 ft by 12 ft. Allowable stress design (ASD) format. Determine building weight. Typical Roof ceiling dead load: Roof truss top and wood frame house utilizing a bearing wall system of light-framed Steps to Determine Seismic Load on Residential Decks Using ASCE. 7-10 (all

To use this calculation, you need a copy of the tables found in the book "Wood Decks: Materials, Construction and Finishing," published by the Forest Products Society in 1996. The square foot area calculated as described translates directly into post size on the table. The weight of a simple roof over the deck is taken into

From strength and hardness, to color and long lifespan gives you the best option for your deck. (pronounced EE-pay) is the finest quality wood decking material available. From the Weight: Basic specific gravity (oven dry weight green volume) 0.85 to 0.97, air dry density 66 to 75 pounds per cubic foot. A 3 4" thick

The Titan post anchor is the most advanced hidden wood post anchoring system of its kind. The anchor is This calculator determines the size of each tributary area of your deck. It then If it is, you must increase the size of the footing to spread the weight out over a greater surface area or increase the number of footings.

If you know the number of board feet replace the default value of 1000 with the known quantity, and the result will equal the actual

Weight. wood decking has specific gravity of 0.85 to 1.08. Air dried density is 66 to 75 lbs. per cubic ft. A 3 4" thick finish material weights approx. 4.5 lbs. per sq ft.

If your deck or porch sags or bounces, it needs some attention from a professional contractor. Consider Small holes in the wood could be a sign that insects, like carpenter bees, are causing structural problems.

overall deck width. See DECK FRAMING PLAN for definition of deck length and width. 3. Minimum post size is 6x6 nominal and maximum post height shall be in accordance with Table 4. 4. All lumber shall be coated steel with coating weights in accordance with ASTM B 695, Use Table 2 to determine allowable joist

The term “deck” refers to different types of floor construction including wood, metal, concrete and composite type construction. RISAFloor uses the term “deck” when . These tables assume 18 gauge deck for all cases when calculating the self-weight, which is conservative in most instances. For the Verco composite decks

What to look for when calculating deck load. Even when we know what a deck's weight load may be when building it, we don't build decks to the load value of failure. We build decks to Also look up in your building code book, or ask your local inspectors for a chart that shows the species of wood that you want to use.
