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 6,037 3,021 0 2,114 7 2,331 7 Yes <br />1.2 20,144 10,079 4,546 2,509 0 0 0 Yes <br />1.3 3,447 1,725 778 429 0 0 0 Yes <br />1.4 4,725 2,364 1,066 589 0 0 0 Yes <br />1.5 5,506 2,755 1,242 686 0 0 0 Yes <br />1.6 5,300 2,652 1,196 660 0 0 0 Yes <br />1.7 3,310 1,656 747 412 0 0 0 Yes <br />1.8 20,146 10,080 4,546 2,510 0 0 0 Yes <br />1.9 10,508 5,258 2,371 1,309 0 0 0 Yes <br />1.10 3,250 1,626 733 405 0 0 0 Yes <br />1.11 4,324 2,164 976 539 0 0 0 Yes <br />1.12 2,127 1,064 480 265 0 0 0 Yes <br />Totals:88,823 lbs 44,443 lbs.18,682 lbs.12,428 lbs.7 2,331 7 <br /> <br />Table 7.1 -Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />11/04/2024 <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 />1330 E Seventeenth <br />St4/10/2025
