EIx = effective flexural stiffness of strongbacks and straps (Table 4.5) (N mm2) a = distance of the element to the closest end of joist (mm) A = effective shear area of blocking (mm2) G = effective shear modulus of blocking (N/mm2) hcw = distance from centre of subfloor to centre...
A look at an actual current joist span table will show that depending on the wood species, the allowable spans for a 2x8 floor joists with 40 pound live load with deflection limit of span/360, ranges from 10'5" (Western red cedar) to 12'9" (Doug fir-larch). ...
I would do every joist so the floor has an even distribution of stiffness. Not sure what you mean by staggering, I’d just use an 8′ long piece at mid-span, both sides of the web. 3′ is more than enough, 4′ spacing willl likely work well as well. Craig Walker says: August ...
Subtle changes in floor usage or joist spans may also result in floor performance complaints. One common problem area is a kitchen with an island, where a homeowner may notice rattling dishes or ripples in a glass of water. A change in joist span at a bay window may also be a trouble s...
Table R507.9.1.3 (1) “Deck Ledger Connection to Band Joist” under the 40-psf-live-load column to determine if the tabulated maximum spacing of bolts or lag screws would apply to connecting a deck ledger to the end verticals of the trusses through the 2x4 ribbon blocks. This table ...

First, determine the size, the spacing and span, and the species and lumber grade of your floor joists. Look for a stamp on the joist that indicates the lumber's species and grade. Use adesign value tableto find the Fb value for your floor joists. As an example, consider a room with...
