saddle design

saddle design

saddle design

(OP)
what are the last resort when we are designing horizontal vessel containing saddle structure

Trial 5: Move saddles to A = 0.2L and saddle angle= 120 and design ring stiffeners in the plane of the saddles

if vessel is not stable inspite of using 3 stiffners right over the saddle

next step is to increase the shell thickness

if my shell material is exotic material, client will not allow me to increase the thickness also

can you guys please give me any guidance to how make vessel structurally stable

RE: saddle design

Maybe give a sketch? I don't understand what your issue is. If complete ring stiffeners don't fix the local support problem then it sounds like it may not be a local problem. How is your vessel failing?

RE: saddle design

Assuming you're working your way through the Zick analysis- there are a number of different variables, different options, and different stresses. In order to use the design method effectively, you have to understand which variables affect which stresses. If you can locate the original paper by Zick, or the discussions of the method in the vessel design handbooks, that will help.

In general, where the problem is overstress in the shell itself, you'd widen the saddles, increase the saddle angle, add wear plates, etc., depending on which stress was exceeded.

RE: saddle design

Hi
Might help if you gave us a picture or drawing of the set up you're having a problem with.
Re read your post and then think if all you knew about the problem is what you have written in that first post how would you answer it.
