Usually solid wood blocking or cross "X" wood blocking. Attached pic is ceiling joist, not floor, but show what I typically do. Usually I stick it in somewhere around mid-span. For me, the solid blocking takes longer to install, but I tend to feel it makes things more solid (don't know if that is true or not).
Re: I Joist Blocking i mean for intermediate blocking just like u would for 2x joists also for if there was a wall above. mainly the question is can u nail into the sides of the flanges for any reason
Blocking, short pieces of 2x stock the same depth as the joists, stops sideways deflection and ties the joists together so they can effectively share floor loads. Tom installs a row of blocking in the joist bays at mid-span whenever a span exceeds 9 feet.
Blocking between joists or trusses is used at the ends of the floor joists or trusses (or a continuous band joist can be used at the ends) and where walls occur above or below.

Re: Floor Joist Bridging Vs Blocking I used metal strap bridging for years and was never happy with the results, except for the drive in type that gives the same benefit of wood X in regards to joist shrinkage.
Deck Blocking And Bridging Blocking or bridging can be used for a variety of purposes in deck building. Probably, the most commonly used technique is to install small pieces of material in a zig-zag pattern between the perimeter joists to create a rigid rim joist that prevents bounce and increases the strength of the rail attachment.
Below is a table giving the minimum size floor joists needed for 16″ and 24″ on center (o.c.) spacing when using #2 lumber with 10 pounds per square foot of dead load and 40 pounds of live load.
In other words, the distance between any two rows of blocking, or any one row of blocking and the end of the deck, cannot be more than 8 feet. As long as blocking meets this requirement, it does not necessarily have to be centered over the length of the floor joists.

I just watched an episode of "Ask This Old House" which dealt with cross bridging between wood floor joists of a house. Tom Silva explained that the cross bridging transferred the load on the joist to the other joists, thus strengthening the floor. ... I can see solid blocking providing more load transfer than the 1x4's. I think the most ...
The blocking also keeps the joists evenly parallel for alignment and nailing of dimensional sheet goods such as decking and gypsum board. If a floor displays excessive squeaking I would be asking the builder why he didn't use panel adhesive between the joists and the decking and screws instead of nails.
This aligns the joists with perfect spacing. Outside joists may not be spaced at 16”oc or may need to adjust to get the proper fit for decking. Leave outside joists for last and install blocking from underneath.
Blocking, when applied to an engineered floor system, provides lateral support between floor joists and can serve different purposes. For one, it is designed to prevent floor joists from ‘’rolling...
Blocking for wall framing are short pieces of 2 by 4 that you install between two joists of the basement ceiling. It's not a "building code" thing and it's not optional, you'll more than likely have to install some blocking to complete your wall framing.
True 2 x 6 joists, but due to settling there was quite a bit of sloping. I put in an additional girder to support it where it is, and I've sistered additional 2 x 6s to bring everything level again. The room is 12' wide at it's widest point.
Blocking and load sharing of floor joist have been discussed here many time. No concensous has evry been reached. General agreement is that blocking is for laterally stabilizing the joist.
Re: Floor Joist Blocking Lateral restraint at supports is required to be by solid blocking or by nailing to a band joist. Mid-span bridging (or blocking) in this instance is not required by any code I know of or by accepted engineering practice, nor would this kind of bridging/blocking contribute anything meaningful to the deflection resistance of the design which already has a maximum deflection of over L/1000.
I joists would use a piece of I joist for blocking). Two 2x4's installed in an X could also be done, and I've seen that with engineered joists, but check with your local building codes to be sure it complies.
