4.0 Design Loads - Dead: <br /> <br />There are two categories of dead load used to perform the structural analysis of the PanelClaw racking system; Dead Load of the Array (DLA) and <br />Dead Load of the Components (DLC). <br /> <br />DLA is defined as the weight of the entire array including all of the system components and total ballast used on the array. <br /> <br />DLC is defined as the weight of the modules and the racking components within an array. The DLC does not include the ballast used to resist loads <br />on this array. <br />4.1 Dead Load of the Arrays: <br /> <br />Array Information Results <br />Sub- <br />Array <br />Name <br />Number <br />of <br />Modules <br />DLC <br />(lbs.) <br />DLA <br />(lbs.) <br />DLC <br />(lbs.)/module <br />Sub- <br />Array <br />Area <br />(ft.^2) <br />Sub-Array <br />Roof <br />Pressure <br />(DLC) (psf) <br />Sub-Array <br />Roof <br />Pressure <br />(DLA) (psf) <br />Max <br />Allowable <br />Pressure on <br />Roof (psf) <br />Acceptable? <br />1.1 29 2,601 3,677 90 1,005 2.59 3.66 3.76 Yes <br />1.2 25 2,256 3,234 90 866 2.61 3.74 3.76 Yes <br />1.3 28 2,520 3,563 90 970 2.60 3.67 3.76 Yes <br />1.4 25 2,251 3,196 90 866 2.60 3.69 3.76 Yes <br />Total:  107 9,627 lbs.13,670 lbs. <br />*Racking component weight range between 13 to 15 pounds per module <br />Table 4.1 - Array Dead Loads and Roof Pressures <br />07/16/2024 <br />APPROVED FOR CONSTRUCTION <br />8 <br />PanelClaw, Inc., 1600 Osgood Street, Suite 2023, North Andover, MA 01845 <br />(978) 688.4900 - www.panelclaw.com <br />2130 N Grand Ave <br />10/1/2024
