      In rectangular tanks, the interactions of exterior walls with fluid, backfill soil and foundation soil convert the earthquake behaviors of these structures into a fairly complex problem. However, when the literature about the structure systems within the scope of the study is investigated, in general, it is seen that there appears a deficiency related to earthquake calculation and design of the exterior walls which interacting with soil and fluid. The main purpose of this study is to propose numerical and analytical approaches for investigating the earthquake behaviors of fluid-exterior wall-soil systems using the approaches proposed in the literature for consideration of fluid and soil interactions, and to investigate the validities and usabilities of the proposed models by means of in-situ modal tests. Furthermore, examining the earthquake behaviors of the said systems via the approaches which appeared to be sufficient, it is also aimed to investigate the effects of both interactions on structure behavior.

      Consequently, in this study, the validities and usabilities of analytical and numerical models via in-situ modal tests were investigated. Furthermore, it was seen that fluid and soil interactions can significantly change the earthquake behaviors of rectangular tanks depending on backfill geometry and/or existence of backfill, embedment shape, height of fluid and the mechanical properties of foundation/soil system.
