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 />(psf) (DLC) <br />(psf) <br />Sub-Array <br />Roof <br />Pressure <br />(psf) (DLA) <br />(psf) <br />Max <br />Allowable <br />Pressure on <br />Roof (psf) <br />Acceptable? <br />1.1 49 4,416 11,686 90 1,689 2.61 6.92 20.00 Yes <br />1.2 48 4,303 9,096 90 1,656 2.60 5.49 20.00 Yes <br />Total:  97 8,719 lbs.20,781 lbs. <br />*Racking component weight range between 13 to 15 pounds per module <br />Table 4.1 - Array Dead Loads and Roof Pressures <br />05/02/2025 <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
