A deck pier block is in many ways just a simplified version of a “precast foundation”, a foundation type recognized by building codes. They're subject to all of the same requirements as a typical footing, regardless of not being cast-in-place. The small bearing area of pier blocks is limited in supporting much load.

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.

Can I use 2x4 for shed roof?

What size lumber can span 20 feet?

Re: 20 foot clearspan beam size In that case, you need something like a 12-16" GLULAM or LVL to span the 20' and can use simple 2x8-10 dimensional lumber 16"OC as floor joists.

What size beam do I need to span 10 feet?

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.
