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
Any storage or occupancy in the attic area?
I am leaving the office right now, can I get back with you later this evening after I get home?
Thank you, ***** ***** you later
Sorry for the long delay!
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.
You can use a W8x24 (50 ksi) steel beam for your 15’ span. This beam is 6.5" wide, 7.875" deep and weighs 24 pounds per foot of beam.
If you reduce your span to 13', you can use a W6x25 (50 ksi) steel beam. This beam is 6.125" wide, 6.375" deep and weighs 25 pounds per foot of beam.
