| What Size Steel Beam? I am adding 600ft to my ground floor home. We have Adobe clay soil and I just completed a pier and grade beam foundation. The piers were drilled to bedrock at 10ft and the grade beam is 8" thick. I am planning to frame my floor joists using 2x8 lumber which will be set on top of the foundation on 3 walls and joist hung off the existing house foundation on 1 wall. I have one long span of 21'-6" that will need a perpendicular support. The span of the support is 23'-4" and I would like to use a steel beam rather than adding anymore footings into adobe clay soil. Can anyone advise me on the size of steel beam I will need to order. It will span the entire length of 23'-4" and be supported on each side by attachment to my new foundation. Thank you for all suggestions. |
