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
Do you have electronic copies of the plans you could share with me?
Let me know when you come back online
Sorry for the delay.
What city and state are you located in?
You said you could share your plans with me?
There is a button on the Chat Window that allows you to attach files.
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 engineered wood options for your 21’ clear span beam:
5-1/2” x 18” King Beam 30F-E4 DF/SP
7” x 18” 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.
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 are removing a large portion of wall.
