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 11,151 5,421 2,539 1,255 0 0 0 Yes <br />2.2 11,143 5,417 0 3,792 6 4,550 7 Yes <br />2.3 24,526 11,923 0 8,346 13 9,100 14 Yes <br />2.4 40,105 19,497 0 13,648 21 14,950 23 Yes <br />2.5 27,182 13,215 0 9,250 15 9,750 15 Yes <br />2.6 38,496 18,714 0 13,100 21 13,650 21 Yes <br />Totals:152,604 lbs 74,187 lbs.2,539 lbs.49,392 lbs.76 52,000 80 <br /> <br />Table 7.1 -Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />10/16/2024 <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 <br />11/13/2024
