5.0 Design Loads - Wind: <br />5.1.1 Global Wind Uplift Summary Table: <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 />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 3,926 1,600 356 2,940 1.93 OK <br />1.2 6,034 3,888 356 3,998 2.18 OK <br />1.3 6,611 11,380 416 7,623 4.79 OK <br />1.4 7,799 12,264 386 4,005 3.48 OK <br />1.5 6,786 11,153 416 3,860 3.69 OK <br />1.6 4,984 9,889 386 3,088 4.34 OK <br />1.7 9,228 9,778 386 3,443 2.39 OK <br />1.8 8,108 8,254 386 3,441 2.40 OK <br />Total:53,476 lbs.68,206 lbs.32,397 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 />07/09/2024 <br />9 <br />PanelClaw, Inc., 1600 Osgood Street, Suite 2023, North Andover, MA 01845 <br />(978) 688.4900 - www.panelclaw.com
