what is the maximum length of timber beam for practical/transportation purposes?
(OP)
I have a 50' long platform. Can I have 2 - 25' timber beam?
In steel we usually have 38' as maximum per transportation.

If this is a follow-up to the last platform question, piles may be longer, but the platform framing itself you'll want to keep the lengths down around that 18-20 feet to ensure availability.
A call to the local lumber yard would confirm that.

should I have 4 timber piles/posts and splice the beam at the posts location?
Or can I have 3 timber piles at 25' distance and splice the beam somewhere in the middle?
I read it's not ok to splice the beam in the middle and should be at the top of the post

Do what Mike says. but if your platform is similar to the photo you posted (or is a replacement for that platform) then 2 ply 2x8 seems light.
Post your intended framing plan and we can comment with more accuracy. What did you choose for a design load in the end?
RE: what is the maximum length of timber beam for practical/transportation purposes?
I'm looking at deck beam span length (table R507.6). it seems 16' or 18' seems too long for 40psf. Should I be looking at 5 or more timber piles and 3-ply beam?
I probably will use 100 psf live load.
RE: what is the maximum length of timber beam for practical/transportation purposes?
100 psf is a good design load for something as you showed in your other post. I would also get equipment weights for anything that will be supported by the platform, the point loads may exceed the effect of the udl in certain areas.
RE: what is the maximum length of timber beam for practical/transportation purposes?
I'm confused because the beams are connected by plate and bolts.

i saw this detail wood pile to beam detail from FEMA but doesnt this look difficult field cutting top of pile?

Will your wood piles be square or round. I don't have much experience with them but I've seen them round in most cases.

I should be connecting the transverse beam to top of pier.
Then connect the longitudinal beam to the transverse beam. I saw that detail in pedestrian bridges.

Why attach to the top of the pile? Consider heavy 2.5 CCA timbers on the side of the pile, bolted with heavy galv. carriage bolts.

There is nothing wrong with the steel connections you have found in the wood manual, but once you talk to the heavy timber guys that actually build this I would expect them to ask why they need these. These require more planning since we (engineers) usually ask for shop drawings, and then they have to wait for them to be galvanized. Then if something goes wrong on site and they have to field modify, then you have a new problem to deal with. If your loads require such a detail, fine, but if not, I would try to avoid the complexity.
Thru bolts in the field are not all that easy unless you allow a greater tolerance for the bolt holes. We usually get asked to sub lag screws on both sides, since very few timber framers have the drill press below that will allow one to consistently drill thru a large timber accurately on site.

Did you talk to any framers as another posted in the other discussion? That will save you a ton of time with all of this. If it were glulams, our supplier will engineer all of the connections and they have specialty designers on staff that are great at dreaming up connection details.
