The dimensions of load area 1 are 4’x3.25′ and equals 13 square feet. The dimensions of load area 2 are 6’x3.25′ and equals 19.5 square feet. And since the deck is symmetrical, the load areas 5 and 6 on the opposite side of the deck are identical. This leaves the load areas 3 and 4 in the center area of the deck to be determined.

The following formulas may be used to calculate deflection under uniform load, or allowable loads based on deflection requirements. Single span: Two-span ndition: Three-span ndition: where: ∆ = deflection (in.) w = w LL = uniform live load (psf) — Or — w = w TL = uniform total load (psf) EI = Bending Stiffness Capacity (lb.-in.2/ft.)

now Let's find the tributary areas of a deck. To determine the maximum load capacity of your deck, start by calculating its total area and multiply by 50 psf. So, a 100 sqft deck would be designed to support 5000 lbs. Do not get nfused with what weight you might think or want to load the deck with.

Dead load of attic floor when floored = 20 lbs. per sq. ft. (Storage space.) Dead load of partitions = 20 lbs. per sq. ft. of floor area Dead load of partitions = 20 lbs. per sq. ft. of floor area Dead load on sOkaynd floor = 20 lbs. per sq. ft. Dead load of first floor, ceiling not plastered = 10 lbs. per sq. ft. Dead load of first floor

Dead Load: 5 lb., 7 lb., 10 lb., 15 lb., and 20 lb. When you click “Calculate Maximum Horizontal Span” at the bottom of the entries, the system will give you the maximum span for the information you’ve entered. Because the calculator goes beyond the limits of grade, live load, and dead load in the DCA 6 and IRC tables, you can design

This calculator determines the size of each tributary area of your deck. It then determines the total load from each tributary area based on the design load of your deck. Default is 50 psf which you can change. The total load for each tributary area is then divided by the area of each footing in order to determine the load psf imposed on the soil.

50 psf x 12 ft = 600 pounds per lineal foot. roof dead load: 10 psf x 12 ft = 120 pounds per lineal foot. total load: = 720 pounds per lineal foot. Girder Example.

Deck Support Bea. Beam Span Chart Table. The span of a beam is dependent on a few variables: The grade and species of lumber, size of lumber and the load it carries. Fewer posts on upper-level decks are typically more desirable to the occupants and this drives the use of larger framing materials for longer spans.
