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 17,953 11,686 525 6,328 1.67 OK <br />1.2 18,411 9,096 525 9,838 1.71 OK <br />Total:36,364 lbs.20,781 lbs. 16,166 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)/(0.6)WIND LOAD <br />05/02/2025 <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
