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 7,604 6,037 350 2,276 1.82 OK <br />1.2 19,681 20,144 N/A 0 1.71 OK <br />1.3 3,416 3,447 N/A 0 1.68 OK <br />1.4 4,548 4,725 N/A 0 1.73 OK <br />1.5 5,490 5,506 N/A 0 1.67 OK <br />1.6 5,267 5,300 N/A 0 1.68 OK <br />1.7 3,281 3,310 N/A 0 1.68 OK <br />1.8 20,097 20,146 N/A 0 1.67 OK <br />1.9 10,309 10,508 N/A 0 1.70 OK <br />1.10 3,221 3,250 N/A 0 1.68 OK <br />1.11 4,288 4,324 N/A 0 1.68 OK <br />1.12 1,950 2,127 N/A 0 1.82 OK <br />Total:89,152 lbs.88,823 lbs. 2,276 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 />11/04/2024 <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 />1330 E Seventeenth <br />St4/10/2025
