Talk:Steel dam

Note... a very early draft of Ashfork-Bainbridge Steel Dam (a red link in the article) can be found at User:Lar/Ashfork-Bainbridge Steel Dam ... still needs a lot of work but hope to go public with it soon. ++Lar: t/c 04:02, 23 January 2006 (UTC)
 * Nice article, but it seems to concentrate exclusively on US. Were there any steel dams built elsewhere? Zocky | picture popups 09:09, 23 January 2006 (UTC)
 * Um, I had some glimmerings that there were some somewhere, in doing my research but I was not able to substantiate any so I did not add them. A draft version had something along the lines of "there were rumors of these built elsewhere" but that was too mambypamby for my taste. I'd love it if someone else could find some info on any! Also a recent change to the article overstates the importance of the one ref, some of the material was learned from the various Redridge Steel Dam sources. ++Lar: t/c
 * My recall (from a engineering class in Montana) is that the Hauser Dam date is off, a check of a web site (http://www.uq.edu.au/~e2hchans/steel_da.html) confirms this. I will edit. Ralph 23Jan05 —Preceding unsigned comment added by 24.113.115.244 (talk • contribs) 21:21, 23 January 2006
 * Thanks, right you are. I put the link in the article in further reading. Strangely enough, this Queensland University research paper is one I already found, and linked in to Redridge Steel Dam (which I did first) but forgot about for this article. Bureau of Reclamation "firsts" page confirms the 1907 completion date as well. Any leads on non North American dams? Thanks!!! ++Lar: t/c 02:54, 24 January 2006 (UTC)


 * Struck link to my user area as the article Ashfork-Bainbridge Steel Dam is live. + +Lar: t/c 22:35, 13 April 2006 (UTC)

Scalloped plates
for what it's worth...

The scalloping on the plates is to handle the hydrostatic forces; if you push evenly on a flat plate, it will bend out like that. If you push on a plate bent into a cylindrical segment, then you have pure tensile stresses in the curved segment and it doesn't get bent in or out.

These dams seem to have used this technique instead of having stiffeners to divide the plate panels into smaller stiffened segments; that would work too (and is how aircraft and ship hulls are built; flat plates with transverse and longitudinal stiffeners), but is probably more expensive to fabricate, and for a static structure like this in which there's no flow to be disrupted by the scalloping there's no reason not to do this.

highly favourable economics
I highly doubt this, since I know some planned dams but none as a steel dam and it's whithout reference. --Mutter5 (talk) 06:58, 28 December 2022 (UTC)
