What size micolam beams needed so I can remove lally columns in my cellar?
Hello all,
I am in the process of finishing my cellar and I would like to remove 2 lally columns that are supporting the 1st floor and 2nd floor in the middle of the house. The beam now is made of 3 2x12's and the span is 18' long supporting 2x8x 12' long on top of the beam. What I would like to do is to leave the beam there and add a microlam to each side and bolt and glue it all together. Would this be enough support without any sagging? What would be the size of the 2 beams needed to support the floor? Any suggestions would be greatly appreciated? Thank you.
