Refer Clause 4.2.2.3 in AS 1684.2 The spacing and span of joists that support the decking are identified in most Building Codes. There are three ways to determine deck joist span and spacing – formula, calculator, and joist sizing and span tables. The height off the ground, wind-load, snow-load, soil-load capacity, and potential seismic forces also factor into the span. Free-standing decks don’t have a ledger. Elevated decks often require greater post and beam support for shorter deck joist spans. The carrier beam runs perpendicular to the joists with its center at 8 feet from the house and the cantilever beyond its center point is 2 feet. The width, thickness, wood type, grade, and spacing influence the span a joist can bridge. Cantilevered joist to wood sill in accordance with Figure R505.3.1(5) Steel plate spaced at 4 feet o.c. Some formulas take the bending, compression, and breaking values for wet or dry wood that are based on predetermined values for different species to determine safe loads over specified distances.

Attached decks require a ledger for securing it to the building, while free-standing ones need an additional beam and post framework. However, cedar will gray with age and requires cleaning and sealing or staining regularly. The more elaborate the deck design, the greater the need for the input of a Structural Engineer. The dead load is the weight of all the building materials and is commonly calculated at 10psf. The span is the distance a joist traverses from ledger to beam, or beam to beam, without support.
