very easy to use also this book tables (if you find the book): they are giving you the stresses of the protection steel pipe but you should be able to calculate the loads over the pipe and the laying conditions (tables sample included)...

www.concretepipe.org you can download from resources - design manual

i worked on prestressing machines for concrete pipes (AWWA C301 Lined and/or Embedded - max inner diam 144"- length 6 meters): the stoppers were rubber- rollers touching the front sides of the pipes, but, frankly speaking the forces were, let's say, negligible. for LittleInch : Same thing if you...

I ran the program "Pipecar" with the data of your doc : result is overflow

having just a look to the mentioned ASCE standard, I have many doubts that the installation conditions (that is bedding type) will be only type 2 for such a great diam and depth of fill. Furthermore there is something strange to me : "page 1 - reinforcing layers 1" whilst "page 2 cage...

I think the ref standard is this

https://resources.concretepipe.org/eriksson-pipe Pipecar software has been superseeded by Eriksson software. Pipepac is available also free on-line (https://resources.concretepipe.org/pipepac)

I found on web this manual (I downloaded free) : there are a lot of cases and loads. Tomorrow I will look better which one is suitable fo you

JStephen : your interpretation is correct. Thks

any suggestion or previous threads (calcs, I mean) on RHS used as supports il truck loading ?

in Italy connection between barriers is done with Diwidag bar. See detailed DWG https://mega.nz/folder/ZudiWLgR#LctrGSk9iwCrIUvdZaPDYA/file/YvcwELLZ

another possibility

as alternative solution you can dowload (free)this publication/manual https://www.steelconstruction.info/images/9/9b/SCI_P292.pdf https://files.engineering.com/getfile.aspx?folder=34989d78-03a3-4e69-95b2-666438513415&file=klein.jpg

I found different numbering but something similar. Furthermore it keeps in account the different values of "J" of column and horiz. beamhttps://files.engineering.com/getfile.aspx?folder=9cb22a1b-6630-4cf6-9275-cddf692738a7&file=Kleinlogel_2.pdf

you can youse (free download)the software "CANDE"

may be you can have a look to "Stress concentration factors - Pilkey - to the chapter related to -shoulder fillet on non-circular contour in a flat stepped bar-"

you can do the reverse : 1 - you pick up some data from the curves 2 - with those data you can find a formula that generates the curve 3 - with that formula (after checking that it complies in an acceptable way) you can edit as many data as you like

FEA : no structural program allowed, but it looks like that I am the winner. Where I have to go to withdraw the prize ?

for me point A will go up because there will be a moment in A due to that A is not a hinge, whilst the point opposite to A can rotate freely
