The following <br /> design conditions for the analysis are based on the site conditions or according to the minimum code <br /> requirements: <br /> Tank capacity 3143 Cu.Ft <br /> Existing tank Construction: 3/16"welded steel walls <br /> Basic wind Speed: 110 MPH <br /> Wind Exposure/Importance: B/Iw=1.0 <br /> Seismic Site Class: D <br /> Soil Baring capacity: 2,000 PSF <br /> Plate steel of existing tank: A-36 <br /> The existing tank will be used for water storage only,the tank construction was analyzed for the highest <br /> loaded exiting tank components to demonstrate it is strong enough to meet current requirements. It was <br /> found to be stronger than the minimum requirements for water tanks and pressure vessels per the current <br /> ASCE requirements. New welded brakets are proposed for anchorage to the slab footing,this welding is <br /> required to meet AISC standards for full penetration fillet or backed up welds((E70XX electrodes). <br /> For tank anchorage, seismic controls lateral design and the slab design(including up lift and overturning <br /> moments transferred to the slab). The Simpson"Wedge All"rated anchor bolts are used, so no anchor <br /> embedment calculation was done. <br /> Speical inspection required: 1.Form work for dimensions,2.Rebar size and placement, 3.Anchor <br /> installation. <br /> If you have any questions_or are in need of further assistance please feel free to call. <br /> �r sc� <br /> J <br /> 9 add <br /> ,,, "0.97 A <br /> ,fy <br /> , „ OCT <br /> 042019 <br /> 4, -$ - . -i. ,- VERETT <br /> 4 0- CITY OF E <br /> Permit Services <br /> Peter Chopelas PE <br />
