Can you take a look at the following link and answer the questions at the bottom of the sheet? Your answers will allow me to accurately model the loading and size your beam. Thanks
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.
For Beam #4, you can use an S4x9.5 (50 ksi) steel beam for your 7’ span beam. The beam is 2.75” wide and 4” deep. It weighs 9.5 pounds per foot of beam length.
You will need to provide solid mechanical connections of each of joists to the top of the steel beam. This will provide the needed lateral bracing of the compression flange of the steel beam. You will need to have a local engineer size your column supports, connections and foundations.
