Abstract:

The May 1983 Coalinga Earthquake provided an opportunity to correlate earthquake performance of cylindrical liquid storage tanks with behavior observed in laboratory shaking table experiments. A 38. 5 ft diameter steel water tank which developed typical 'elephant's foot' buckling has been found to be a good prototype for a 12 ft diameter aluminum tank. The properties of the prototype and model are correlated. From these relationships, the measured dynamic stress response of the model is extrapolated to obtain the stresses induced in the prototype.
