I have a main beam (~6 x 8 inch solid wood)spanning approximately 20 feet, being supported at the ends by the basement walls and in between by two brick columns. Settling of the basement cement floor (over fifty years worth) has resulted in the beam, and subsequently the entire house, 4-5 inches down in the center. I have started to slowly (1/4 turn of jack per week) raise the beam at its lowest point and hope to ultimately build up the columns after I have reached the appropriate level. I am wondering if this is a sound plan and if the newly straightened, longstanding bowed, beam will maintain the new shape. Also, is it possible to replace he beam and how would you do it. Any advice is appreciated.
Thank you,

Go ahead and jack up the beam, Remove the brick pillers and break out the floor, dig down 24" and 30" square. Pour a new pier with a post base, Replace the piller with a 6x6 treated post. Bolt the post to the base and use 2 tie straps from the beam to the post. Repeat with other piller.

If you want to replace the beam you will have to support the floor on both sides of the existing beam, with beams and bracing.
