Hazardous Waste Tank Sys <br />Written Assessment per CCR Title 22 <br />Chase Chrysler Jeep, Stockton, CA <br />March 9, 2011 <br />Seismic Calculations: Seismic calculations are made using tank <br />measurements, weights, configuration and local seismic design forces to <br />determine if there is sufficient anchorage to prevent the tank from moving or <br />overturning in the event of a maximum designed earthquake. The calculation is <br />made using FEMA 450, ASCE -7 and the California Building Code standards. <br />Chase Chysler Jeep <br />Waste Oil Tank Seismic <br />Cylindrical, Vertical, Closed Top <br />Material of Construction: Steel <br />Shell Height, in <br />61.500 <br />Diameter <br />38.500 <br />Volume of Tank, in3 <br />71559.324 <br />Volume of Tank, gallons <br />309.781 <br />Working Volume, gal <br />278.803 <br />S.G. of contents <br />0.950 <br />Weight of Contents, lbs <br />2208.953 <br />Tank Wall Thickness, rrm <br />3.300 <br />Tank Wall Thickness, in <br />0.130 <br />Wt of Tank, lbs <br />305.930 <br />Total Weight of Tank and Contents, lbs <br />2514.883 <br />Zip Code <br />95212 <br />Height of CG, in <br />27.675 <br />Overturning Moment Arm, in <br />27.675 <br />Resisting Moment Arm, in <br />19.250 <br />Ss <br />0.751 <br />SI <br />0.269 <br />Soil Class D <br />Fa <br />1 .200 <br />Fv <br />1.862 <br />Sms <br />0.901 <br />Sml <br />0.501 <br />Sds <br />0.601 <br />Shc <br />0.334 <br />To <br />0.111 <br />Ts <br />0.556 <br />E, steel, psi <br />29000000.000 <br />I, in4 <br />56987.809 <br />k, Ibf/in 233904361.650 <br />T, sec <br />0.013 <br />a <br />1.000 <br />Sds <br />0.601 <br />Rp <br />2.500 <br />Importance Factor <br />1.000 <br />Fp <br />241.751 <br />Fp min <br />453.282 <br />Fp max <br />2417.507 <br />FP min rules <br />453.282 <br />Overturning Moment, inlbf <br />12544.593 <br />Resisting Moment, inlbf <br />48411.496 <br />Resisting Moment > Overturning Moment <br />No Tension on Anchors <br />Qe <br />453.282 <br />pOe lbs <br />453.282 <br />2Sds D <br />302.188 <br />E <br />755.471 <br />U=1 .2D+1 .0E+.5L+0.2S <br /># of bolts <br />1.000 <br />Vu lbs/bolt <br />453.282 <br />Tu - lbs/bolt <br />-7.333 <br />No tension <br />U=0.9D-(1.3W or 1.0)E <br />Vu lbs/bolt <br />453.282 <br />Tu - lbs/bolt <br />-654.770 <br />No tension <br />Shear Strength of Anchor.
