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 />1.1 104 8,095 11,681 78 3,576 2.26 3.27 100.00 Yes <br />2.2 255 19,868 34,016 78 8,788 2.26 3.87 100.00 Yes <br />2.3 276 21,606 33,407 78 9,502 2.27 3.52 100.00 Yes <br />2.4 184 14,454 26,060 79 6,334 2.28 4.11 100.00 Yes <br />2.5 270 21,014 32,196 78 9,303 2.26 3.46 100.00 Yes <br />Total:  1089 85,037 lbs.137,360 lbs. <br />*Racking component weight range between 13 to 15 pounds per module <br />Table 4.1 - Array Dead Loads and Roof Pressures <br />03/20/2024 <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 />1851 E Deere Ave - 101118504 & <br />20182282 <br />4/11/2024
