Project:POE Marine Industrial Expansion By:KCP <br /> Location:Everett,WA Date:5/6/2021 <br /> Low-Mast Footing Design <br /> This calculation is to design the spread footing for the low-mast light poles. Light pole base reactions are provided by the light pole manufacturer and <br /> are used as the demands at the top of the foundation pedestal.The pole reactions are based on the capacity of the pole(by others)and are listed on <br /> S1.1. <br /> N�—� sEE sPEaPicnnoNs <br /> i <br /> �m <br /> aiiz-ECRou, <br /> PER NOTINTE..PRISE o .YEL"W Ae�ERr <br /> Rear.PER�z z-om Aa�nE <br /> TOP 01 P"El—SEE <br /> `a <br /> SEE E—oE1u� Ae IT <br /> ,z ruin csec LLaow ExcevnnoN <br /> COMPICTED <br /> SV1—E CL A EC POLE <br /> &r000No <br /> Soil Properties <br /> Yconcrete 150 pcf <br /> Ysoil 120 pcf <br /> ciail—able 620 psf Per Geotech Report <br /> PP—we 250 pcf Geotech Report,Neglect first foot of soil <br /> IAsliding 0.35 Per Geotech Report <br /> Foundation Properties <br /> hpedestai 7.0 ft Height of Pedestal <br /> Dpedestai 3.4 ft Diameter of Pedestal <br /> hsoil 3.0 ft Height of soil above top of footing <br /> tFTG 36.0 in <br /> LFTG 13.0 ft <br /> htotal=hstem+trrG 6 ft <br /> Vehicle Barrier <br /> Lba iEr 8 ft <br /> Bbarrier 5 ft <br /> hbarriEr 8 ft <br /> Weights <br /> WPedestai 9533 Ibs <br /> WFTG 76050 Ibs <br /> Wbarrier 48000 Ibs <br /> Wsoii 57571 Ibs <br /> Wtotal 19115S Ibs Total Weight at bottom of footing <br /> Driving Forces <br /> Seismic Force <br /> Fseismic=psesimic(htotal)2 705 Ibs <br /> Mseismic=Fseismic(htnta1/2) 11161 Ib*ft <br /> Wind Force <br /> FLLSurcharge-PLL.Surcharge(htotal) 1100 lbs <br /> MLLSurcharge-FLL.Surcharge(htotal)/2 22000 Ib*ft <br /> 10 <br />
