Özet

In this article, linear elastic static and linear elastic dynamic analysis of two-dimensional structure-foundation-reservoir problem is discussed. Mechanical interaction between structure-foundation-reservoir and discretization of these regions are simulated by reliable numerical Finite Element Method. The reservoir region which incorporates the compressibility effect and surface sloshing motion of water is formulated by two-dimensional Lagrangian fluid finite elements. The dynamic responses of the structure under a given ground motions are obtained in three conditions: structure-reservoir interaction with rigid foundation, structure-reservoir interaction with finite region of flexible foundation and structure-reservoir interaction with including the infinite region of flexible foundation. During dynamic analysis, only the radiation conditions toward infinity and energy dissipation in foundation is simulated considering infinite elements in the infinite region of the flexible foundation. The results of dynamic analysis obtained from structure -foundation-reservoir interaction are shown without considering the radiation conditions in the infinite region of the constant depth reservoir. And only the static and dynamic displacement responses of the crest are given in this paper. All steps of static and dynamic analysis are performed using FORTRAN 90 coding language. The static and dynamic responses are validated and compared with the results of other research papers.
