I need to support a residential floor at mid span with a uniform

Customer Question

I need to support a residential floor at mid span with a uniform load. The clear span of the beam is 16' 7". the total square footage of the floor above is 380. at 40 lbs per square foot I figure the load is 15,200. I would like the depth of the beam to be 8" so I can flush frame. what size beam should I use?

The smallest beam you can use (assuming you detail the joist connection to brace the beam laterally) is a W8x31 ASTM A992 Gr. 50. The beam is 8" deep x 8" wide and weighs 31 pounds per foot.
