i am soliciting for information on retrofitting my home with a steel i beam. my home was constructed in the early 1920’s, and is a wood frame consstructed on a brick foundation with a basement. The house is single story with plaster walls and cielings 10′ high. gable roof.the floor is framed with 2x8s 16″oc, cieling joists are 2×6″ 16″oc, rafters are 2x4s 24″oc . i plan on creating some additional living space in the future in the attic wich is currently unfinished. the house measures 24’x45′ and is currently supported by a solid timber member 8″ tall by 6″wide, this member is set into the masonry walls on either end, with 2 splices creating 3 pieces roughly 15′ each. verticle supports are in place under the 2 splices and in the center of each of the 3 timbers creating a max span of roughly 8-9′. my question is on the proper sizing of a steel beam. i am considering using a 8″ 18lb beam made of 3 sections, 2 splices and 5 verticle supports made of 3″ schedule 40 steel pipe. can anyone give me any advice on this subject, is this beam big enough ? what size of footings should i pour under each of the verticle supports? any advice would be greatly appreciated.

You are asking a bunch of anonymous people for detailed structural engineering advise about a building none of us have seen. You are going to risk your money and safety on that advise. Doesn't that seem a bit odd? Lots to risk to save a few bucks.
You can get good advise from a local engineer, sometimes from the steel fabricator or maybe from a local contractor. These folks have their reputations and legal liability on the line.
