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 10,416 11,151 N/A 0 1.78 OK <br />2.2 11,929 11,143 525 1,845 1.81 OK <br />2.3 26,024 24,526 525 5,243 1.91 OK <br />2.4 44,125 40,105 525 7,653 1.80 OK <br />2.5 28,704 27,182 525 3,474 1.78 OK <br />2.6 41,939 38,496 525 6,524 1.79 OK <br />Total:163,137 lbs.152,604 lbs. 24,739 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 />10/16/2024 <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 <br />11/13/2024
