This report presents results from a series of static and dynamic tests. The investigation includes a shaking table study of essentially the same broad tank model tested in the first phase of this research program, but provided with more comprehensive instrumentation. It also includes a static tilt test study and measurements of the geometric imperfections of the tank model. The influence of such parameters as the base fixity, a cone roof at the top, the type and amplitude of the ground motion, and the stiffness of the foundation material on the response is studied. Finally, the observed behavior is correlated with predictions made using standard design procedures. The investigation demonstrates the need to incorporate in the design a reliable prediction of the uplift and high-order response, including the influence of the foundation material, together with a more realistic failure criterion.
