Dynamic Experimental Investigation on the Fundamental Frequency of Liquid Storage Tanks under Seismic Excitations

Abstract:

A large-scale earthquake simulation experiment about the unanchored cylindrical steel liquid storage model tanks has been completed. The fundamental frequency of the model tank with liquid inside was investigated based on the experimental data of the acceleration dynamic response. The seismic table test, the analysis methods are designed and conducted, and experimental results of the model tank were carefully measured. Furthermore, national design standard was used to calculate the fundamental frequency of the model tank system. The reasons for the existence of consistency and differences between the results obtained from experiments and national design standard were discussed.
