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 3,692 1,884 0 1,319 3 4,550 7 Yes <br />1.2 5,207 2,658 0 1,860 3 13,650 21 Yes <br />Totals:8,899 lbs 4,542 lbs.0 lbs.3,179 lbs.6 18,200 28 <br /> <br />Table 7.1 -Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />06/01/2023 <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 />P- 40 <br />1901 N Fairview St & Bldg A, B, <br />C, F & 1919 N Fairview St Bldg E <br />4/11/2024
