A southern pine (2) 2x12 beam can span 8 feet when supporting joists spanning a maximum of 14 feet, and it can cantilever 2 feet beyond the posts on each side. With the allowable cantilever of the joists, this beam would support a deck 12 feet by 17 1/2 feet.
PROJECT: STEEL BUILDING DESIGN CASE STUDY. SUBJECT: JOIST SELECTION (ECONOMICAL BAY STUDY) Investigate two framing options: Option I - joists span 30', Option II - joists span 36'. This bay framing study is done for joists (sheets 16-17), interior floor girders (sheets 18-22), and. interior fill beams (sheet 23-24). Comparison bays are priced out (sheet 25) to select economical bay framing.
