5.0 Design Loads - Wind: <br />5.1.1 Global Wind Uplift Summary Table: <br /> <br />The necessity to add mechanical attachments can arise for several reasons. Building code requirements, roof load limits and <br />array shape all may come into play when determining their need. The table below provides the mechanical attachment <br />requirements for each sub-array within this project. <br /> <br /> Applied Load Resisting Load Code Check <br />Sub- <br />Array <br />Name <br />FL = Total <br />Wind <br />Uplift (lbs.) <br />DL = <br />Total Dead <br />Load (lbs.) <br />Maximum Allowable <br />Mechanical Attachment <br />Strength (lbs.) <br />Total MA <br />Capacity <br />(lbs.) <br />Calculated <br />Factor of <br />Safety* <br />Check <br />1.1 23,732 31,077 525 4,440 2.49 OK <br />1.2 18,781 24,544 525 3,520 2.49 OK <br />1.3 27,158 36,075 525 6,929 2.64 OK <br />1.4 22,403 29,997 525 5,405 2.63 OK <br />Total:92,074 lbs.121,693 lbs. 20,294 lbs. <br />Table 5.1 Summary of Mechanical Attachment Requirements <br />* Back calculated factor of safety provided to determine factor of safety applied to dead load in lieu of 0.6 in ASCE 7-16 equation 7, BACK <br />CALCULATED FACTOR OF SAFETY = (DEAD LOAD+MECHANICAL ATTACHMENT)/(.6)WIND LOAD <br />05/24/2024 <br />APPROVED FOR CONSTRUCTION <br />9 <br />PanelClaw, Inc., 1600 Osgood Street, Suite 2023, North Andover, MA 01845 <br />(978) 688.4900 - www.panelclaw.com <br />1895 & 1995 S Standard <br />Ave1/7/2025
