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 3,677 1,857 0 1,300 7 3,648 19 Yes <br />1.2 3,234 1,633 0 1,143 6 3,264 17 Yes <br />1.3 3,563 1,799 0 1,260 7 3,648 19 Yes <br />1.4 3,196 1,614 0 1,130 6 3,072 16 Yes <br />Totals:13,670 lbs 6,903 lbs.0 lbs.4,832 lbs.26 13,632 71 <br /> <br />Table 7.1 -Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />07/16/2024 <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 />2130 N Grand Ave <br />10/1/2024
