What is roof load width?
Roof Load Width (RLW) The size of the roofing material is needed to calculate how much load the roof members and substructure need to support, and therefore what size the underlying timber parts need to be.
How many footings do I need for a 12×20 deck?
Quick Attached Deck Footing Chart
| Size of Deck | Beam Size | Number of Footings |
|---|---|---|

How much support does a deck need?
Before starting to build, the first question is: How many footings do I need for a deck? For an attached 12 x 12′ deck, you’ll need at least 3 footings, plus at least 2 more if you’re planning on building stairs with it. If your deck will be a different size, it’s easy to figure out how many you’ll need.
What is the tributary area of a column?
Tributary area the area surrounding the column that is bounded by a panel centerline. In order to calculate the forces and static loads transferred from floor slabs to the columns tributary area method is used.
