    Hello CEE,
    Much like a movie or a video-game that one enjoys, I have re-watched this video twice already simply because it is (for me) enjoyable to watch.
    23:43 The ability to drag while complex editing in order to create the helical beams was a very cool WOW wow idea indeed. It is the unhinged kind of thinking which the CEE recorder is famous for (time and time again that is 😊). 39:10 YES, lucky there exist the able and willing CEE.
    Thank you for modelling the three configurations side by side, this really helps as it enables pertinent details to be captured and it also opens up the scope of application of the various learned techniques.
    04:00 I concur with the CEE. Riser and threads vary depending on intended use (public buildings, general purpose and fire escapes stairs, access and vertical ladders, etc. various codes and handbooks have own recommendations. I usually use (staircase for general use = 190 risers x 270 threads; or even an easier stair with 175 risers x 280 threads). As the CEE have already noted, one must make a trade-off on the size of the stair thread when it comes to circular staircases.
    15:09 Very informative comments by the CEE editor on the foreshadowed instabilities and stress concentrations associated with (attempted) connection of a staircase to a column using a single point on a shell. 32:43 Thanks for not editing this part out, it is a valuable overall learning experience. 34:45 the statement made by the CEE about analysis issues sums it up; additionally, CEE have on previous videos talked about the importance of thinking about the practicality of the connections…one should ideally also throw this into the mix when designing cantilever staircases.
    22:10 I could not stop laughing when the CEE recorder said ….I call foul…this is cheating…..then boom, the CEE recorder un-cheats big time.
    35:30 😊😊😊
    28:17 I know this video is about modelling and analysis (not yet design), however I am curious that my dry run deflection is about Dis = 5mm, Max=13.2mm, this is so when I am using 10mm steel plates staircases and a 200x75 Parallel Flange Channel as my helical beam. Even if I change the helical beam to an I-Section (W10x12), the dry run deflection is still Dis = 5mm, Max=12.9mm, these values are relatively higher compared to the ones obtained on the CEE tutorial video with a placeholder helical beam of (W10x12 - I think?) and the (later changed/corrected) thickness of 75mm 😊😊😊. I am wondering as to what could be causing this significant difference above? the "exact numbers are not important" it is the currently unknown reasons to me that is the cause of my concerns.
    38:50 Correct, I also use the same effective thickness approximation shown by the CEE with the riser and threads above this thickness becoming added dead-weight (permanent load).
    41:42 if CEE is this impressed, I guess RSAP must be that “...bloody amazing….” ? For the record, even though the triangles ended up (justifiably) edited out, CEE recorder should know that his approximations have so far been works of art and they enhance the conceptual understanding and appreciation behind the subject matter, if (or when time allows), I would gladly take the approximation and then the automation (in that order).
    42:36 I am still in awe that CEE only (😊) take 1hr 20 min to come up with all this from scratch. This is (lightning) quick for the quality of output that the CEE is producing.
    Thank you CEE for sharing your knowledge and for illuminating the year 2022. Happy and prosperous new year to you.
    Looking forward to what is yet to come in 2023
    Regards DK

      Hi Engr. Donald,
      Happy new year ^_^
      I am really happy that you liked it.
      The ability to drag occurred to me live on camera as I was about to add nodes. It worked flawlessly.
      Thnx for sharing the step dimensions you usually use. It helps all viewers to have multiple views on that issue.
      I wanted to actually edit the entire failure out. But then I decided to just keep relevant parts that showcase my absolute failure ^_^. It is only through failures that we learn. To be honest, while I was recording, I was really inclined to say unstable, but gave the model the benefit of the doubt. Anyways, it was unstable.
      oh the eureka moment after the 22nd minute was, for me, a real blast. I enjoyed it.
      Truth to be said, I am concerned about the deflection too. There are still loads to be added. I will keep an eye on that and tackle the problem in my next video. I am pretty sure something is a miss here.
      I will have to look into max sizes for staircases without any mid-span supporting columns.
      Oh the meshing capabilities of RSAP!!! THEY are next level!
      The only reason I removed the "manual" triangle modeling is that I am afraid of people who "spot click" the video to think that this is the way of doing things. It was a nice experience actually, but the cons outweighed the pros to be honest.
      You are always most welcome. A happy new year,
      CEE

    In Algeria we usually use a raiser of 17 cm and a trade of 30 cm

      thnx a lot for the info ^_^ I guess it makes sense.
      So basically a story is around 3-3.5meters high. Interesting.

      yes sir and usually we use a story-high multiple of 17 like 3.06 3.23 3.4 .... etc @@CivilEngineeringEssentials
