7.0 Design Loads - Seismic (Cont.): <br />7.3 Lateral Seismic Force Check: <br />The necessity to add mechanical attachments can arise for several reasons. Building code requirements, roof load limits and array <br />shape all may come into play when determining their need. The table below provides the mechanical attachment requirements for <br />each sub-array within this project. <br />Nomenclature: <br />WP = Sub-Array Weight <br />FPL = Lateral Seismic Force <br />FRL = Lateral Seismic Resisting Force <br /> <br />Array Information Lateral Force Verification Results <br />Sub- <br />Array <br />Name <br />WP <br />(lbs.) <br />FPL <br />(lbs.) <br />FRL <br />(lbs.) <br />0.7 FPL - <br />FRL (lbs.) <br />MA's <br />Required <br />Total MA <br />Capacity <br />(lbs.) <br />MA's <br />Provided Acceptable <br />1.1 11,681 5,679 2,660 1,315 0 0 0 Yes <br />2.2 34,016 16,537 0 11,576 18 12,350 19 Yes <br />2.3 33,407 16,241 0 11,368 18 18,850 29 Yes <br />2.4 26,060 12,669 0 8,868 14 9,750 15 Yes <br />2.5 32,196 15,652 0 10,956 17 15,600 24 Yes <br />Totals:137,360 lbs 66,777 lbs.2,660 lbs.44,084 lbs.67 56,550 87 <br /> <br />Table 7.1 -Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />03/20/2024 <br />APPROVED FOR CONSTRUCTION <br />14 <br />PanelClaw, Inc., 1600 Osgood Street, Suite 2023, North Andover, MA 01845 <br />(978) 688.4900 - www.panelclaw.com <br />1851 E Deere Ave - 101118504 & <br />20182282 <br />4/11/2024
