Awesome explanation and visual graphics!

Not a huge deal, but the link in the description doesn't quite work. Good luck with getting your tools out there!

[@StructuralCentral]

Thank you so much for pointing that out! I added https to the URL and now UA-cam correctly identified it as a link, so it works now.

Yes! It's actually in the works right now and should come out in the next couple of weeks. You can subscribe so that you are notified when it is released.

What is you are asked to calculate live load using elastic method? For instance,Bolts group design. A bracket plate is connected to a W-shape column. The layout of bolts group is 5 by 2 (5 rows and 2 columns). A325 bolt, 3 inches spacing vertically and 5.5 inches spacing horizontally, type N, loading case S, 7/8 inches diameter. Eccentricity e=16 inches. If the dead load DD is 10kips, what is the maximum live load LL?

A c channel is bolted eccentrically to a concrete wall and the unbolted side of the c channel is supporting a cable tray. The bolts are 6 numbers in 2 columns 6 inch apart. How do I know if it would be acceptable if we reduce the 6 inch to 4 inch (between the bolts)

[@StructuralCentral]

It is not possible to determine if the reduced spacing will be acceptable with the information that you have provided. It's necessary to know the magnitude and location of the load from the cable tray, the bolt size and material, the channel size and material, and the details about how the bolt is anchored into the concrete wall. Decreasing the spacing between the bolts will result in increased reactions, thus decreased load carrying capacity. I recommend you hire a local structural engineer to answer your question. Best of luck to you!
