You're welcome! There's multiple possible configurations for connections with cap plates so I can't really make a general comment about their design. Is there something that you were specifically wondering about?
The strength of each individual bolt is the minimum of its bearing, tearout, and shear strengths (including safety factors), so you must make sure that this exceeds the applied shear force. An example connection with 3 bolts is discussed in the video at 6:12. The applied load cannot exceed 62 kips. (This is just considering the bolts, so the actual connection strength may be lower when you consider the other limit states.)
Sorry, but I don't offer anything like that. University programs are where you can get a broad understanding of the structural engineering field. Here's also a great list of books and resources for each of the common structure types. www.eng-tips.com/faqs.cfm?fid=2189
Hi, Can you post a video on 2 side/3side displacement of a base plate with stiffner plate/bracket along with the tension/shear force and moment resolved tension force on bolts
Thanks for the suggestion! I always appreciate hearing what people would like to see next. I am planning on making a video about the design of baseplates. Subscribe so you don't miss it :-)
Check out the commentary for Section J3.6 of AISC 360-16. The paragraph right after they show Equation C-J3-4 discusses everything that is shown in the video about determining Fnv. I hope that helps!
The threads do not affect the bearing strength of the bolted connection (ΦRn = Φ C d t Fu). You get to use the same value for the bolt diameter, d, regardless of where the threads end up in the joint. AISC 360-16, Commentary Section J3.10 states: "...the same bearing value applies to all joints assembled by bolts, regardless of fastener shear strength or the presence or absence of threads in the bearing area." The thread location only affects the bolt shear strength (ΦRn = Φ Fnv Ab). When the threads are located at the shear plane, the value for Fnv that you get from Table J3.2 of AISC 360 has a 0.8 factor built into it to account for the reduced cross section. (Fnv for Group A, A325 bolts is 68 ksi when threads are excluded from shear planes instead of 54 ksi when threads are NOT excluded from shear planes.)

Thank you for the high-quality video! Theoretical videos with good graphics and clear explanations for Steel Design are lacking on youtube.
No problem! I'm happy to be able to fill that niche.

Thanks for the nice explanation.
Thanks for the comment! I'm glad you found the video to be helpful.
Thank you very much for your this video. I would appreciate it if you could clarify the column cap plate connection design check.

Thanks for the video.
Can you do a video for slip critical connections too.
That's a great suggestion! It's already on a list of potential future videos along with a video about prying action force on bolts.
Valuable Video 🤩 after we calculate the bearing and tearout and shear resistance have we compare it with shear force on the bolt?
The strength of each individual bolt is the minimum of its bearing, tearout, and shear strengths (including safety factors), so you must make sure that this exceeds the applied shear force.

Please do an Video about Erection Sequence of Main Steel & Misc
Thanks, I always appreciate suggestions :-)
Can you share where you got the uneven load distribution equation for the bolts at 1:48min in the video??
Thanks!

How to calculate the bearing stress if threads are not excluded as shown in the right joint when the video is at 2:12?
The threads do not affect the bearing strength of the bolted connection (ΦRn = Φ C d t Fu). You get to use the same value for the bolt diameter, d, regardless of where the threads end up in the joint.
AISC 360-16, Commentary Section J3.10 states: "...the same bearing value applies to all joints assembled by bolts, regardless of fastener shear strength or the presence or absence of threads in the bearing area."
