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.

I need to know Floor Joist #3 span distance (even if you do not have floor joists) from my sketch, then I can run some numbers.

How many questions does my $36 cover this week?

I have another question on another 36 feet span garage beam size
Expert:  walkereng replied 10 months ago.

I can give you a couple engineered wood options for your 22’ clear span beam:

5-1/2” x 18” King Beam 30F-E4 DF/SP

5-1/4” x 18” Versa-Lam 2.0 3100 SP

These are Boise Cascade products and you can go to the following link to find distributors in your area.

You will need to have a local engineer detail your connections, size your support columns, determine foundation requirements, and check your structure’s lateral stability due to the fact that you will have a large opening in your existing exterior wall.
