Re: Wide Flange Steel Beams for Roof
Remote Name: 22.214.171.124

Question: We have purchased 2 Sea-Can 40' x 8' x 8' containers. They
are set 25 feet apart. We would like to build a roof over both the 'cans' and
the space between. What size of wide flange steel beams would work in this
application and how many beams would we need? There are 8' stub walls built on
the inside edge of the Sea-Cans giving us 16' of clearance inside. The roof will
go up from there approx 6 in 12 for pitch. The cans have roof sections built
over them approx 5 in 12.
Builders Websource® Answer: Before any structural analysis is
possible, several clarifications are necessary:
- What is the application for this proposed structure? Residential?
- Is the 25 foot separation from the outside edge of Sea-Can #1 to the
outside edge of Sea-Can #2, or is the 25 foot separation the inside distance
between the two containers?
- What is the snow load in your jurisdiction? From your IP address, it
appears you're in the Whitehorse area of the Yukon Territories. We found one
reference to a snow load of of 183 Kg/Square Meter. However, this should be
verified with your building department (if you have one).
- What roofing material do you intend to use on the pitched roof? Please
specify proposed thickness and type of decking material as well as roof
covering (eg; 3/4" plywood, metal roofing, etc.). The thickness of the decking
will vary depending on the distance between the rafters. For example, rafters
on 24" centers vs. 32" centers will require different plywood substrates.
- Your description of the 5/12 pitch and the 6/12 pitch is a little
confusing as well as the stub wall. It would be helpful to see an elevation
view and top plan sketch of your proposed structure. We think we understand
your description, but aren't certain. You can email or fax it to us using the
information in the "contact us" section of this website.
- Are there any other loads you expect to have, such as storage and will
there be any interim supports for the roof ridge?
With a little more information, we can point you in the right direction.
