Using 2" by 10" floor Joist and 3/4 osb. 16" on center the I beam w 8 by 15 will carry 11 feet. I need okay on size from a structural engineer to take to the building inspector.
Structural Engineer: walkereng, Consultant replied 10 months ago

OK, so 11' clear span, what are the 2x10 floor joist spans off of each side of the proposed steel beam?

Thanks, ***** ***** me the information I need.

I’d like to point out that a Professional Engineer’s standard of care typically includes a site visit to assess field conditions and get an overall understanding of the structure. This can obviously not be accomplished through the internet. The information provided here is meant for planning purposes only (general sizing and budgeting) and is based on the information provided by you. All loading cases considered are for vertical loads only, no lateral analysis has been completed. The information should be verified by a professional engineer who can visit the site to ensure that potentially important information has not been overlooked or omitted.

Hold on while I run a few numbers for you.

My assumptions are:

span Length = 12'

tributary loading width = 14'

Live Load = 40 psf

Dead Load = 10 psf

W8x15 (50 ksi) steel beam

Based on the assumptions listed above, the W8x15 (50 ksi) steel beam can span the maximum required clear span of 12'

I have only assumed Live Load and Dead Load for the 1st floor, no attic or roof load has been assumed to be carried by these steel beams.
