What is the ?
Need a bit more info to calculate anything.
Hi! The information you have provided is not enough. Try using some online services like http://concalc.org/ to calculate remodeling details right
I would pay the $700 for a local structural engineer to provide the answer and a spec sheet. Helpful for dealing with the local building permit people.
Then you can decide on what to use for the joist depending upon the available head space. Where it is limited a steel beam is optimum.
