Final Structural Report <br />PROJECT NUMBER: AE230325 | PROJECT NAME: CPT HARBOR ANA <br />ACROS ENERGY | acrosenergy.com | 512.663.9058 | info@acrosenergy.com 10 / 23 <br />Based on 2022 California Building Code 1607.14.4, roof live loads need not be applied to the area covered <br />by photovoltaic panels where the clear space between the panels and the roof surface is 24 inches or less. <br />Therefore, PV load of 9 psf can replace live load. <br /> <br />RAIN LOADS AND PONDING EFFECT: <br />Desing Rainfall intensity i = 2.8 in/h <br />Roof Slope = ¼” / ft (Conservative value) <br />Static head above primary d_s = 4 in <br />Drain bottom level to the roof lefel = 4 in <br />Tributary area A = 5549 ft2 <br /> <br />Flow rate Q = 0.0104 A i = 162 gpm <br /> <br />Therefore, <br />d_h = 2 in (conservative based on ASCE Table C8.3-3) <br />Rain load at the drain location <br />R = 5.2 x (d_h + d_s – drain level ) = 5.2 x (2 + 4 – 4) = 10.4 psf IBC 1611.1 <br />This load decreases to 0 psf within (2 in / roof slope) = 8 ft from the drain <br />Therefore, disallow 10 ft from the roof edge for PV installations. <br /> <br /> <br /> <br /> <br /> <br />
