30' x 30' second story floor span
(OP)
I am helping a church to design a gymnasium. They will build this in a metal building. one end of the building will have a 40' x 65' area with a kitchen, restrooms and a classroom on the first floor and a full class room on the second floor with a 5' walkway that overlooks the basketball court. My problem is trying to find out the sructure for the second story floor. What size beam should I use and what should be the spacing.

Secondly, the information you provided is not sufficient to size a joist for the second floor. The loading in the corridor area will be fairly heavy, 100 to 125 psf, depending on your code.
You may want to consider making some of the walls on the first floor bearing walls, which would involve thickening the slab. This would significantly reduce the size and cost of the floor joists by reducing the spans.
