How can I support a joist length of 9 meters without steel?

Question

I want to convert my loft and need to span 9 meters unsupported. Can it be achieved without steel beams?

Do these need to support a load? Or is it just for the ceiling? — Chris Cudmore, Jun 28 '13 at 17:52

I just checked some Ontario tables. For an Attic, not accessible by stairs (i.e. not used as living space, a 2x12 every 12" can span 32 ft. But you can't put anything above it.

I've found nothing in the tables that allows a 30 ft span supporting a floor.

While this doesn't mean it can't be done, it means you need to consult with an engineer, and pay for a proper design.

I think for a span like that you need to look at engineered joists if not an I beam. – auujay Jun 28 '13 at 16:54
