wood. <br /> Hydrostatic and Seismic Analysis Tank Name/marking: 275 Gal. Waste <br /> Antifreeze Tank <br /> Overhead view: <br /> See Attachment 3 manufacturer's drawing. <br /> (Include all measurements. Does not need to be to scale) <br /> Cross sectional (lateral) view: <br /> See Attachment 3 manufacturer's drawing. <br /> (Include all measurements. Does not need to be to scale) <br /> Please provide a drawing of the seismic/hydrostatic anchorings used and their <br /> spatial relationship to the tank. <br /> Anchoring Assembly Description <br /> The tank is seismically restrained using a SII tank seismic restraint system <br /> recommended for SII 35 — 500 gallon dual containment tank (DCT) systems. The <br /> anchor system is constructed from angle iron (3"x3"x1/4" thick) and 7X19 <br /> stainless steel aircraft cable (1/4-inch diameter). Structural calculations for the <br /> DCT system were prepared by Associated Design & Engineering, Inc. and are <br /> presented in Attachment 3. <br /> At a minimum provide the following: <br /> Calculation of the seismic load of the tank: <br /> 0.63 kips (ASCE 7-16) (Attachment 3) <br /> Calculation of overturning moment of tank <br /> 17.78 k-in (ASCE 7-16) (Attachment 3) <br /> Safety Factor: 7.07 (ASCE 7-16) <br /> Demonstration that the resisting moment is greater than the overturn moment: <br /> Safety Factor = (resisting moment/overturning moment) _ >> 2 <br /> Wood Environment & Infrastructure Solutions, Inc. 275 Gal.
