--------------- = Jrectangle and base on whether this is less than 1 (Self-anchored) to less than (2) Stable with Stress check reqd.

The edges are welded so the shell is welded to top and bottom , hence the full fixity. I was assuming the same that with a 0.5" thick shell the heat flux will be much higher and i wouldn't need to take as crazy a Delta T consideration. The outside temp is higher (or lower with the top and bottom...

It is a Closed Rectangular Tank -
Top and Bottom plates are same thickness and material as the Shell -
The edges are all welded . The tank is resting on a less than 1% slope Skid. There are direct - Anchor bolts to the Foundation.
Tank is Storing Water at normal temperature...
@JStephen Thank you for the response. This tank has a mixer to keep water circulating during low temperatures so don't see Icing being an issue.
What I am bewildered is that zero consideration to these effects is given ? I am coming from another industry so Tank Engineering is very new to me...
I am working on designing a Rectangular Water Storage Tank. (AWWA D-100)
I need to consider Stresses and Load combinations that include Thermal Movement due to Temperature change - *Correction - Design requirement Ambient DeltaT (Effects for Solar heat gain to Night time - sky heat Loss) For...
Update,
I went through the calcs of a rectangular Tank (Not trying to re-invent the wheel) but used Force per unit length from Uplift due to the Seismic force and the force per unit length due to download from the weights of things that can be considered just at the bottom of the shell ( Weight...
@JStephen - Thank you for your response.
I believe the Anchorage Ratio Check J is for the Shell buckling (or need for anchorage to prevent that) API also gives stresses on the plates based on where J lies - kind of reinforcing the requirement and corresponding stress checks to be confirmed if...
*** Long Post Alert***
I am new to the Tank industry but been involved in structural engineering for 12+ years
This is yet another Rectangular Tank Design Question! :rolleyes:
I know these are inefficient but the client wants what the client wants from a space perspective.
Rectangular Water...
I want the Individual Responses to run a Matlab code for a proposed combination something which is not in any of these software's nor in the code and to compare the results and check the validity of the proposed new modal combination method .
I hope I answered to why I am looking to do this .
Hello,
I am trying to find the individual modal responses say for an N mode structure by doing a modal time history analysis for a time dependent Earthquake Loading .
The current results give me the maximum for each element after combining all the modal responses what i am looking for is the...
