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 31,077 15,227 0 10,659 17 11,050 17 Yes <br />1.2 24,544 12,026 0 8,418 13 9,100 14 Yes <br />1.3 36,075 17,676 0 12,373 20 13,000 20 Yes <br />1.4 29,997 14,698 0 10,289 16 10,400 16 Yes <br />Totals:121,693 lbs 59,627 lbs.0 lbs.41,739 lbs.66 43,550 67 <br /> <br />Table 7.1 -Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />05/24/2024 <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 />1895 & 1995 S Standard <br />Ave1/7/2025
