What is the maximum span for a 2x10 floor joist?
With 16” spacing, a floor joist can span up to 14’ as long as it is not cantilevered and terminates with support on either end. If the joists are 24” apart, then one 2×10 joist can span up to 11’ 5”. These lengths are for SYP lumber. If you have Spruce-pine-fir lumber, then your span changes to 13’ 7” for 16” joist spacing.

How far apart are beams?
The beams will be 8 feet apart (joist span). They will be resting on posts. The number of posts depends on how far the beams can span. This will be standard pressure treated lumber. I was going to use screws to hold the beams together. Maybe construction adhesive, too.
How much load is on each beam?
You indicate the beams are 8’ on center, so the total load on each beam is: 50 psf x 8’ (4’ on ea.side of beam) = 400 plf

A beam must be 3 members unless you are getting a PE to do the design for you or you are using southern pine. The beam span also depends what your joist span is between the beams/ledger but lets assume 6' then with southern pine it would be 10' 1".

Can you use 4x6 posts with 2x10 posts?
Also, save yourself the time and trouble building the beam that way if using 4x4's. upgrade your posts to 4x6's and then notch the 4x6 post so the 2x10's can be fastened to each other with no spacer and then they will sit on top of the notched section of 4x6. Run your 1/2" x7" stainless steel carriage bolts through the piece of remaining 4x6 and both 2x10's.
How wide is a 2x12 post?
2" X 12" is the rough lumber dimension before it is run through the planer at the lumber mill. After it comes through the planer it will be 1-1/2" X 11-1/4" (so yes, a 2 X 12 does not measure 2" X 12"). This means that our 4-ply 2 X 12 will be 4 X 1-1/2 inches wide or 6 inches. Therefore a post to support this built-up floor beam will need to be 6" by 6". Framers generally nail together several pieces of dimensional lumber to create such posts. The wood column is nailed to the floor beam above and sits on a concrete pad at its base.
How many feet of supported length?
The supported length shown along the left-most side of the table, is the total length of the floor joists to be supported on either side of the floor beam divided by two. In the case of our example house, the house is 24 feet wide so the house will require a total width of 24 feet of joists. Dividing by two gives us 12 feet of supported length. So we'll read along the table row for 12 feet of supported length.
How to determine supported length of a beam?
Next use the buttons to select the supported length for the beam. (Recall from our discussion above that the supported length for the beam is the length of the floor joists that it will be supporting on either side of the beam divided by two. For example, for a 24 foot wide house with a center floor beam, the total supported length of the floor joist is 24 feet. Then you divide this by two to give a supported length of 12 feet. This is the number you will use for supported length.)
How long are floor joists?
The floor joists are still 12' long but now you can see a floor beam running horizontally across the middle of the house (supported by the lower concrete foundation wall). The picture below shows what the framing for this floor would look like in a three-dimensional perspective.
Do you need a structural engineer to calculate beam span?
In general, if you are staying within the limits of your beam span tables and floor joist span tables, you will not need to have beam calculations done by a structural engineer.
