Thanks for the video! Now I think I can finish my wood structures design class that I took over the summer. Your videos have been a big help on explaining the content that my professor had trouble with.
Would love to see this beam problem done as an ASD or LRFD exercise for sizing and selecting single or multiple LVL's. I know NDS Chapter 8, "Structural Composite Lumber", applies to LVL's but no one has done a video tutorial on them. In fact written guidance on NDS type calculations for LVL's seem to be nonexistent. Manufacturers offer span tables but not much else. Please consider this, or if you (or anyone else) are aware of references that address this question, kindly advise. Thanks
curious as to why you chose to use an L/600 deflection limit and not an L/360 deflection limit typical of a roof/ceiling system? I know it would pass either way but wondering if there was something I missed :) Thanks for the videos, they are great tolls for PE review!
Wondering if you could help answer a question that I have for a project I’m doing on my house. I’m looking to take out a weight bearing wall and put up a Glulam beam. Not sure if I need to have 1 beam or 2. The beam will span 20 feet. The attic boards are 2x6. The roof is built with no trusses. The outside walls in that area of the house are 24 feet apart Based on the span charts I’ve seen and the snow weight adjustment (35 psf, I’m in Michigan) I figure that I need either a 3 1/4 x 15 or a 5 1/4 x 13 1/2 beam. (Roughly 300. Lbs per linear foot) Thanks for your time Jamie
Hi Jamie, Please note my following response is not suitable as professional advise for any design documents for your home but im happy to provide my thoughts. the 5 1/1 x 13.5 GL should do fine. you should consider if the attic space above the GL is considered light storage space or not - that will add to the loading. Also in this case deflection of the beam will mostly control the design of your beam. If your beam is hidden in the ceiling then its no problem but if you have finishes that may be prone to cracking you may want to consider slightly sizing up your beam.
@@Kestava_Engineering thank you for your response. The attic space is not for storage. I was also planning on the beam being totally hidden in the attic

That means a lot dog, i really appreciate the kind words. let me know if you have any problems added to the video list!
I'm so glad I found your channel today. This is going to be invaluable. I'm subscribing.
Welcome aboard! thank you!
Hi Team! let me know if the video if to potato quality or not. Im still getting the hang of video editing! thanks for every ones patience!
How do you determine volume factor of a fixed end beam of a glulam beam
Thank you
Thanks a lot for this :D
Jose anytime! thank you so much for your suggestion

thank you so much!
N3M4N always my dude
Thanks . Can you calculate CLT floor thickness ? Please
Yes I can!
@@Kestava_Engineering great, I can't wait to watch the video. Thanks
Hi Kestävä, I have a question: What happens if the value of Cv is greater than 1 in my case is not significantly greater but is 1.053?

Great point Summit! L/600 is pretty strict. For a typical floor L/360 would be more accurate

Question: I was following along and using NDS 2018, and the shear formula (pg.17) (3.4-2) = 3V/2bd.
Am I missing something here?
your totally correct Sherwood, at 34:45 he just called V as F and substituted b*d and used the cross sectional area. but its the same equation
@@richracz6221 thank you!!, I thought as much but wanted to verify
You are doing a great job, learned a lot from your videos.Could you please give me your WhatsApp, want to have word with you to learn more.
