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 10,794 11,681 N/A 0 1.80 OK <br />2.2 38,092 34,016 525 8,192 1.85 OK <br />2.3 43,881 33,407 525 11,773 1.72 OK <br />2.4 28,647 26,060 525 4,284 1.77 OK <br />2.5 41,219 32,196 525 9,948 1.70 OK <br />Total:162,633 lbs.137,360 lbs. 34,197 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 />03/20/2024 <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 />1851 E Deere Ave - 101118504 & <br />20182282 <br />4/11/2024
