Hanging Vessel Saddle Analysis
Hanging Vessel Saddle Analysis
(OP)
WE have a project from Aramco where the vessel is hanged from the floor.Attached is the data sheet for the same. My query how can we perform the saddle analysis for this vessel. (WIND, Seismic, ZICK)





RE: Hanging Vessel Saddle Analysis
However you use three instead of two hanger location, this will make the structure indeterminate. Depending on the stiffness of the ceiling the support can have different loads than the considered.
Hope it helps.

Using the analysis for vessels resting on ground will not be correct. The support will be in tension in your application under the gravity loads.
You can use approximation to solve the vessel:
1. Design each ring to take half the vessel gravity load due to the expected deflections on the ceiling under the center hanger.
2. Consider static force due to the wind and seismic forces in two horizontal directions separately.
3. Add the actions due to wind/seismic onto the gravity load on the largest loaded ring, and solve the ring under the combined loading using Roark's Formulas or equations taken from other sources. You may need to solve the actions separately and add them later on the ring.
4. Design the ring section for the combined loading and support conditions considered.

You indicated that the tank is to hang from the floor, therefore, you are looking for steel straps around the tank. Basic engineering calculations for tension and elongation as well as analysis of the attachments of their ends to the floor should suffice.
