RE: ringwall reinforcing design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There is a procedure given in API 650, "Welded Steel Tanks for Oil Storage",
which probably originated at CB&I.  The equations can be derived easily,
basically the procedure is to size the width of the ringwall to have the
same soil bearing pressure as under the tank bottom, and to calculate the
hoop force in the ring due to the lateral earth pressure due to soil and
tank contents.

	I need design a concrete ringwall to support a flat bottom anchored
	The seismic overturn moment and base shear are calculated per AWWA

	My question are:
	How do I size the ringwall reinforcing Torsion and Shear? Is there
	any reference book or standard procedure I can find? Is there any
	instead of FEA?
