Ask Structural Engineering Questions and Get Expert Answers ASAP
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
Sorry for the delay, I have two more questions and then I can size your beam:
1. Is there any storage or occupancy in the attic area?
2. From my drawing, what would be your dimension that I call "Truss Span" at the top of the sheet?
Let me know when you come back online
If you could answer my two questions above, that would be great.
1. There is no occupancy in the attic. There is light storage (no significant load) in the attic.
2. The roof truss span is 24' with no webs connecting the trusses.
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 can give you a couple of engineered wood options for your 10’ header beam:
3-1/2” x 7-1/4” King Beam 30F-E4 DF/SP
3-1/2” x 8-5/8” Versa-Lam 1.7 2650 DF
These are Boise Cascade products and you can go to the following link to find distributors in your area. http://www.bc.com/locations/
You will need to have a local engineer detail your connections, size your support columns and determine foundation requirements.
