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 />1.1 329 26,643 31,077 81 10,765 2.47 2.89 100.00 Yes <br />1.2 258 20,990 24,544 81 8,415 2.49 2.92 100.00 Yes <br />1.3 396 31,902 36,075 81 12,994 2.46 2.78 100.00 Yes <br />1.4 326 26,313 29,997 81 10,681 2.46 2.81 100.00 Yes <br />Total:  1309 105,849 lbs.121,693 lbs. <br />*Racking component weight range between 13 to 15 pounds per module <br />Table 4.1 - Array Dead Loads and Roof Pressures <br />05/24/2024 <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 />1895 & 1995 S Standard <br />Ave1/7/2025
