I'm currently planning to build a 24'x32 shop with a second floor for lumber storage and a possible office.in order to have the most head room and not have a real tall profiles was hoping to use I- joists for the 24 , span instead of lvl,s or beams. I'd like to avoid any posts in the first floor also. Is this a viable option or should I use a beam with joists on hangers? How thick would a 24' I- joist be? Any advice would be greatly appreciated for newbie builders!
The work is DIY-able, but the sizing of the timbers will not be; you will also need to consider overall stability, particularly if there is a 2nd floor and you are using it for storage. This is not a simple garden shed and you would be better getting a scheme drawn up by an SE
contact your local lumber yard and inquire about the size of the I-joists. most lumber yards will have a professional engineer they use to size engineered wood products and provide any engineer's certification that may be needed by the building department (at least in my area they do).
as an option you can look into floor trusses (ask your lumber yard) by checking out the yellowpages for a local truss manufacturer.
