0 0 <br /> Structural Assessment <br /> An additional component of the assessment was completed by Structural Engineers,Inc. (SEI) <br /> to satisfy section 66265.192(a)(5),specifically: <br /> (a)(5) design considerations to ensure that: <br /> (A) tank foundations will maintain the load of a full tank; <br /> (B) tank systems will be anchored to prevent flotation or dislodgement where <br /> the tank system is placed in a saturated zone, or is located within a seismic <br /> fault zone; and <br /> (C) tank systems will withstand the effects of frost heave. <br /> Section(a)(5)(C)does not apply at the site. <br /> Inspections of the existing concrete floor system did not indicate any distortions, cracks, or <br /> settlement in the tank pad area. Considering the tank system has been located in the same <br /> relative position for approximately 19-years confirms the tank foundation is adequate to <br /> maintain the tank load. <br /> The used oil tank is a shop-fabricated tank with an integral support system using 2 steel <br /> saddle-type supports welded to the tank cylinder. A manufacturer's attached plate indicated <br /> "This tank is provided with an integral steed foundation and is intended for stationary <br /> installation only." The tank is anchored to the existing concrete floor using steel angles and <br /> anchor bolts. See the Structural Detail Plan and Sections in Attachment C for the tank and <br /> anchoring details. <br /> Structural Engineers,Inc(SEI)performed an assessment for the used oil tank's existing <br /> seismic anchoring system and determined the anchorage to be in Code compliance.
