BigInch, really thanks for your support...
your attachments are very useful, but please bear with me with some extra questions:
1- In the spread sheet when you talk about growth temp between two anchors,,, you put a standard straight beam ...
But, in our case we have a loop between the two...
Ahh, so you hate to say LOOP,,made me just google about meaning of bent for a time !!!
Ok, waiting you after couple of days,, with a great examples :)
Happy Chrismas, hope that you spend it with all your beloved ones.....BUT Don't eat the whole Turkey... ^_^
REGARDS
In my case I've put an anchor between each loop, so of course i don't have problem with that.
As for your way in calculations, sorry but I don't get it !!!
You said "Put a roller support between each bent and at one end to make it a determinate structure"
What did you mean by the bent ?? and...
Canadieng, thanks for the graph,
yes its clear that there are differences between the three ways,
And as I've know and noticed in the graph that KELLOGG is the nearest one to computerize results !!
BigInch, other guys,
If we back to the force calculated by Grinnell
Fx = 120.45 lb, Am I true...
BigInch,
Thanks for reply,
Please find attached:
- Line Digram with 3 loops, before loops its only straight line with two ended anchors.
- C-12 Kellogg Chart
- ITTG, Table
- cantilever
After looking to C-12, ITTG table, you'll recognize the directions of forces and moments.
As for the...
Good day,
I have Just confused when i am doing some calculations of forces and moments affecting on the expansion loop,
Pipe Data:
10" X 0.365", API 5L X52
Moment of Inertia: 160.8 in^4
Diff in temp (btw installation and operating) = 165 C = 329 F
Thermal Coefficient = 6.72 x 10^-6 in/in F...
