Ensure your splice plates are sized to fit between the worst root radius of the two sections and provide steel shim plates on one side to account for the difference in web thickness. With a 3" flange you wont be able have more than one row of bolts top and bottom.
Unlikely to be any...
I'm not familiar with these capacity plots, bu how could the pile achieve the correct "set" when at 36ft the capacity is 290 Kips yet at 37ft it is zero.
I would expect some friction resistance, which completely disappears by driving another ft?

I find it very strange that the axial capacity is reduced the deeper the pile is driven?
There is almost 3 times the capacity at 35ft as there is at 50ft.
This doesn't make sense to me

See a contractor use this form of construction on a culvert in Africa. I would never advocate this.
The timbers will decay during seasonal weather patterns and compaction will be poor leading to settlement of the culvert and road.

Your on the right track.
The doors being open will create a negative internal pressure co-efficient. Combined with the external pressure will give you the lateral load.
1.5KN/m2 would not be unreasonable for 2.4m high wall panel of structure with dominant openings.
When checking the capacity...
Had a similar building a number of years ago.
Considered the combined beams as suggested above. In the end it was more economic and much easier to construct a raft slab.
