A study of liquid storage tank seismic uplift behavior
The earthquake response behavior of a 6 X 12 ft model cylindrical liquid storage tank was studied at the Richmond Field Station, Earthquake Engineering Research Center in the University of California, Berkeley earthquake simulator laboratory. This study included static tilt and dynamic shaking table tests using both a rigid mortar foundation as well as a flexible ''simulated soil'' rubber foundation. It is observed that the state-of-the-art mathematical representation of tank bottom plating using a one dimensional beam element with the formation of two plastic hinges, while neglecting both radial catenary tension and support foundation stiffness, poorly predicts the true displacements and stresses recorded in these experiments. There may exist serious implications for the adequacy of aseismic design regarding tank bottom plate rupture and wall buckling resistance. The development of an ''empirical tie element model'' is given which includes the consideration of catenary tension and foundation stiffness parameters. The purpose of this formulation is to arouse discussion leading to an improved treatment of this problem. It is not intended to supplement current practice.
