Just finished having a 16' high 40'x40' addition built on to an existing polebarn. I wanted to build a loft over 1/2 of the addition for storage. Want to design for a 100lb/sqft liveload. My plan was to duplicate the endwall poles placed on 8ft centers with doubled 2x12 plates to rest 20ft engineered lumber joists on 16" spacing covered with 3/4 t&g plywood. Does anybody know of a link to get the loading and span distance for engineered lumber or better yet if my design will get me to my live loading target.
