steel beam to carry live loadFrom: jdphaneuf73@yahoo.com

CommentsI want to determine if a steel I-beam may be an option to carry a span of 12'. The project consists of opening up a load bearing wall in a 26X30 Cape. From front to back the house is 26' and the wall is about 16' from the front and 10' from the back. The trib. would be 13'. The load consists of the roof, and a live load upstairs. I have had calculated that four 1-3/4"x 7-1/4" VERSA-LAM beams are insufficient failing both live load and total load deflections 136% and 116% allowable respectively. The finished ceiling height in the room is 7'4" and therefore the beam I put in can not be too wide. (ex. the 11-7/8" LVL was not an option although 3 of them did calculate to be sufficient for carrying the load.
I am looking for a 12' steel beam that will fit into a pocket of 3-1/2" and preferably be narrow enough to allow head room below the opening in the door. 6"-8" perhaps?
