What is the maximum span for a 2x8 floor joist?
Also know, what is the maximum span for a 2x6 floor joist?
Max. Live Load 30 lbs/ft2 (1436 N/m2)
|Maximum Span (ft - in)|
|Nominal Size (inches)||Joist Spacing Center to Center (inches)||Lumber Grade|
|2 x 8||12||15' - 10"|
|16||14' - 5"|
|24||12' - 4"|
Subsequently, question is, how far can a double 2x10 span without support? When supporting joists that span 12 feet with no overhang beyond the beam, a double ply beam can span in feet a value equal to its depth in inches. A double 2x12 beam can span 12 feet; a (2) 2x10 can span 10 feet and so on.
Beside above, how much weight can a 2x8 joist hold?
some of it gets pretty technical in nature, and mostly relates to pounds / square foot of loading. 2x6s are generally used for ceiling joists, esp since you said 24" oc and reallllly short spans only (5 or 6 feet ). Most floor loads would be a minimum of 2x8 @ 16" oc and most preferbaly 2x10.
How long can floor joists be without support?
A live load of 60 pounds per square foot demands more support and shorter spans. Spaced at 12 inches, the joist may only span 16 feet 8 inches. At 16 inch spacing, 15 feet 2 inches and 13 feet 3 inches at 24 inch spacing.
