Ask Structural Engineering Questions and Get Expert Answers ASAP
I can help
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
1. What city and state for possible snow load?
2. Any storage in the attic area?
3. Horizontal distance from Beam #5 to ridge?
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.
Thanks, ***** ***** headed into my office right now (West Coast time) and can get back with your around my lunchtime today, if that is OK?
Let me try running some numbers quick before I leave.
This question is covered until you get the answer your need and are happy with.
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.
