AST drawing ( provided/drawn : source) (see attached) 6 . Design Standard (ASME, UL, etc . ) UL 142 -S, il ele Wall Steel /Mfr: Ace Tanks 7. AST foundation (describe) concrete sub-floor, AT sits within a steel berm. Base of AST under UL 142 adequate to withstand the load of a full tank4ank is anchored to wall. 8 . AST anchoring (seismic zone/floatation risk) AST is anchored, with a steel earthquake strap around the tank with '/� in. anchor bolts anchored into the concrete wallwith the steel strap being set at approximately 14 inches above Y2 of the heieht of the tank. . Stockton is a (groundshaking/ potential liquefaction) seismic region , These anchors are intended to secure the tank during a seismic event. There are two scenarios which would create loads upon them . The first scenario is an empty tank. With an empty tank, the expansion anchors resist the overturning moment through their tensile (Pull-out) capacity. Since the anchors are installed at the perimeter of the tank, the distance between anchors (in either girection)provides a sufficient lever arm for the concrete anchors to not exceed their allowable pull-out capacity. The second load case is with a partially full or full tank. In this scenario, because the liquid fills the bottom of the tank and increases its weight, the governing load case becomes the shear capacity of the concrete expansion anchors In the shear loading, all anchors resist the loads and their allowable capacity is not exceeded. This load case is conservative in its analysis since it neglects the friction force created by the weight of the partially full or full tank. This tank' s rear is set in a corner, against the concrete walls, which further acts as a barrier to movement in the event of an earthquake. AST is situated in secured lubricants room, at the Northern side of Service area. The tanks are unlikely to move outside the room in a seismic event or a flooding event
