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 11,686 5,869 0 4,109 7 11,050 17 Yes <br />1.2 9,096 4,568 0 3,198 5 13,000 20 Yes <br />Totals:20,781 lbs 10,438 lbs.0 lbs.7,307 lbs.12 24,050 37 <br /> <br />Table 7.1 - Summary of Mechanical Attachment Requirements <br />* MA's Required = 0.7 FPL-FRL/MA strength <br />05/02/2025 <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
