I am trying to build a work shop using three 40' steel high

Customer Question

I am trying to build a work shop using three 40' steel high cube shipping containers that will be joined together. We plan to cut the sides out of each of the two outer and inner containers and weld them together. We then plan to having five vertical posts, two 10' and one 20' span on the interior with beams spanning the interior to hold up the ceilings. There will be no roof structure added other than the current standard flat metal roof that will be coated. There will be 1/8" joining plates welded in on the upper roof and bottom using 6010 and 7018 rods. The units will be sitting on 16" x 48" concrete piers on 10' centers length wise and the vertical posts will be centered over those piers on the interior. Question is what size vertical posts and what size beams should we be planning for? We'd like to go with wood which makes it easier to mount things on, but can go metal if required. It will be located in Bellingham, WA 98229.
JA: OK. Is there anything else the structural engineer should be aware of?

Can you post a sketch?

Hold On...

Okay...Sent. I think...

Did you get them?
Customer: replied 6 months ago.
I should probably clarify something...We won't be supporting ceiling drywall, etc. The beams and posts are strictly there to replace the structure from the walls that we will be cutting out when we join the three containers together. So all in all, there will be 4 10 foot beams, two 20 ft beams and 8 posts.

Shoot. I think I sent you the wrong interior post layout file. Let me re-send. The revision added the two exterior most posts and wider foundation piers...

I apologize for the delay. I didn't get a notice that you had responded.

What are the plan dimensions of the shipping containers?

Customer: replied 6 months ago.
See attached dimensional drawing for a single container. I plan to join three for a total exterior dimension of 40' x 24' x 9'6". The interior dimensions and weights are also given per unit.

Here is a more detailed drawing I found...
Expert:  StructuralEng replied 6 months ago.

The posts can 4x6 doug-fir no. 2 and the beam can be a 5.25" x 14" 2.0E LVL.

What about Steel?
Customer: replied 6 months ago.
remember, there is a beam at each junction where the left and center and the right and center containers join.
Expert:  StructuralEng replied 6 months ago.

In that case you can use 5.25" x 11.25" 2.0E LVL instead of the 14"

Expert:  StructuralEng replied 6 months ago.

Steel can be W8x15
