So you have a single story with a basement, is the proposed beam in the basement supporting the floor joists, or is the proposed beam on the 1st floor supporting the ceiling joists?

its supporting floor joists
Structural Engineer: walkereng, Consultant replied 2 years ago

One more question, the best way for me to check you floor beam is for you to tell me how far you want to span and then I can run numbers with your configuration.

What is the span you want for your steel floor beam that will support your 1st floor joists?

Sorry for the delay.

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.

Structural Engineer: walkereng, Consultant replied 2 years ago

Since you say the exterior wall to the center of the beam is 12' and the beam length is 17', I am using 17' as your beam span.

A W8x18 steel beam will not work for your 17' span.

You can use W8x24 (50 ksi) steel beam for your 17’ span. This beam is 6.5" wide, 7.875" deep and weighs 24 pounds per foot of beam.

This is assuming that your beam carried to load from the 1st floor joists and your ceiling joists. I ASSUMED THAT NO ROOF?SNOW LOAD WILL BE CARRIED BY THIS PROPOSED BEAM.

You will need to have a local engineer detail your connections, size your support columns, and determine foundation requirements.
