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 https://docs.google.com/open?id=0B3LjUB_rxIbcNVlreGljdFZUZ3kxTHhvVDFnRV9uQQ

Sorry for the delay. I have a couple more questions:1. You answered question #3 "roof load transferred to walls", is that trusses that clear span the interior walls and rest all of their weight on on the exterior walls?2. Is there any storage or occupancy in the attic area?
Customer: replied 1 year ago.
No clear span load transfer to outside wallsNothing in attic as it is all 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 am assuming this proposed 14' span beam will be supporting the 2nd floor joists, a wall on the 2nd floor and the 2nd floor ceiling. I am assuming NO roof/snow load is transferred down to this proposed beam. I can give you a couple of engineered wood options for your 14’ span floor beam:3-1/2” x 14” King Beam 30F-E4 DF/SP5-1/4” x 11-1/4” 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/#!/building-materials-distribution You will need to have a local engineer detail your connections, size your support columns and determine foundation requirements.
