ASYMMETRIC UPLIFT ANALYSIS OF UNANCHORED STEEL STORAGE TANKS
During severe earthquakes, the most important parameter affecting the response of unanchored tanks is the uplift of their base plates from the foundation. This study mainly focuses on obtaining the overturning moment-base rotation diagram of unanchored tanks. To this end, a method is introduced which is based on the uplift of tapered beams. Then after, the accuracy of the method is examined by the experimental investigation of a broad tank model. Finally, a simplified non-iterative method is introduced which can accurately predict the uplift response of unanchored tanks.
