We have determined that ihe Connection Plates and Licbec� Stand (per Pigurc 2, <br /> attached) is adequate to trans(er and resisl the total design seismic (orces as prcscrihed in Section I G32 of <br /> ihe 1997 Uniform Building Code suhject to the tollowing assumptions: <br /> • Glycool DE-192G Weighl: 22A5 Ib <br /> • Glyrnol DE-192G Height: Approximately 66 inches to the center o(gravity (including siand hcighU <br /> • Equipment frame construction is adequate to act as a single unit during a seismic event <br /> • All components of the Glycool DE-192G are attached to the frame and within the outer shell enclosurc <br /> of the Glycool DE-192G and does not pose a life safery hazard. <br /> • The Liebert Stand will provide both graviry and laceral support and the Glycool DE-I92G will be <br /> at:ached to the frame per Figure 2. <br /> • The 7/R" diam. leveling leg will have an unrestrained height not exceeding 2�h " per Pigure 2. <br /> • We understand the Ooor supponing tlie Clycool DE-192G is a concrete slab, the Liebert Frame should <br /> be anchored directly to the concrete Ooor wi�h Simpson Sleeve-All Anchurs (ICBO ER 3631) per <br /> Pigure 2. <br /> • If ihe iloor supponing the Clycool DE-192G is a raised access tloor, the seismic resistive brackets <br /> should be designed to iransfer all lateral, overturning, and compression (urces �o the coucre�e slah <br /> supporting the raised access floor. <br /> If you liave any ques�ions c,r require any additional in(omiation, please feel free to call our o(fice. <br /> Sincerely, <br /> ADS Consuhing, <br /> EQE St uctural Gngincers Division S C p� <br /> � �— ��G �FW�sy��'9� <br /> Stephen Ting, P.[� ~ '" � <br /> Project 8ngineer /� <br /> ,� � . <br /> ,P 17359 <br /> ��y� ��j. • � �.�� <br /> �NAL ' <br /> Jim DeSalvo, P.E. <br /> Group Manager e�s 7/_p/� � <br /> AB56 Conwltlnp Inc. • 1411 Fourth Avenue Bldg.,Suile 500 • Seattle,WA 98101 USA • Tel:208-621-P6B7 • Fex:208�824•B26B <br /> www.ebsconsutting.mm 0i11M""""` <br /> ` IISEADCFPOIIIOC�UD�sqnlTri�rcMncNlli�hmNttw.dx <br /> 1 <br />
