The linear response of a cylindrical liquid storage tank to the Channel 3:360 corrected record of the Northridge earthquake measured at Arleta cite which has a peak ground acceleration of 0.344 g, was found. The finite element mesh is used is shown in Figure (4.25). The tank has 37 ft. diameter, 32 ft. height, 28.3 ft. liquid height, 3/8 in. wall thickness, and 1/2 in. base plate and roof thickness. Results were compared to those obtained from the analysis presented in reference . Figure (4.26) shows the time history response of the horizontal acceleration of the tank shell top node. Figure (4.27) shows shell base axial stress time history. Figure (4.28) shows shell hoop stress time history at 25% of the shell height measured from the bottom of the tank. Figures (4.29) and (4.30) show the tank base shear and base overturning moment time histories due to pressure on tank wall, respectively.
