I am planning to finish an attic space. I want to eliminate one 4x4 wood column in a line. The column is 8 ft from a load bearing wall and 12 ft from another column (which will remain). The column supports twin 2x10s with a 2x6 joists and 2x6 rafters in a simple low pitch roof above. I can get at the twin 2x10s so I could bolt a microlam or even steel to reinforce this. How can I find out what must be added to eliminate the column? Thanks a bunch!

    Pictures and/or diagram would help. Potential snow load and/or hurricane and/or earthquake issues could be involved as those can all affect code in different areas. Though in the end I suspect the answer will be "consult a structural engineer." – manassehkatz Jan 14 at 21:19
  • What is the span of the 2x6 joist and what spacing? – Lee Sam Jan 14 at 22:58
  • Is there a joint (splice) in the 2-2x10’s at the point where the 4x4 is to be removed? – Lee Sam Jan 14 at 23:01
