Remove bearing wall in residence and install adiquate support steel
Remove bearing wall in residence and install adiquate support steel
(OP)
I have a bearing wall that I would like to remove. The wall supports 2 floor joist spans. 1 span is 10 linear feet and the other span is 21 linear feet. I would like my beam to span 16 feet with a steel support post on each end. This structure is a 2 story house and would like the downstairs to be open completely. I already have a footing under the area I intend to place my posts. I need help determining the size I-beam and support post i will need to carry this area.

Now, your problem is as easy as to calculate a simply supported beam for the proper load and at very low deflection. Proper end connections, columns, and footings are also required.
My recommendation is not to exceed L/1000 total service level vertical deflection, especially if the bearing wall continues above, in which case L/1500 would be even better maximum deflection. If no bearing wall above, you can relax to maybe L/500 if you are ready to take some minor cracks in your structure.
Also, when designing your columns, don't forget to note that the loads are applied eccentrically, at the bolt line. It is not a centered load in the column.
