    Dynamic analysis of dam-reservoir-foundation interaction in time domain
    (SPRINGER-VERLAG) Küçükarslan, S
    In this paper, a time domain dynamic analysis of the dam-reservoir-foundation interaction problem is developed by coupling the dual reciprocity boundary element method (DRBEM) for the infinite reservoir and foundation domain and the finite element method for the finite dam domain. An efficient coupling procedure is formulated by using the substructuring method. Sharan's boundary condition at the far end of the infinite fluid domain is implemented. To verify the proposed scheme, numerical examples are carried out and compared with available exact solutions and finite-finite element coupling results for the problem of the dam-reservoir interaction. Finally, a complete dam-reservoir-foundation interaction problem is solved and its solution is compared with previously published results.

    Transient dynamic analysis of dam-reservior interaction by coupling DRBEM and FEM
    (EMERALD GROUP PUBLISHING LIMITED) Küçükarslan, S; Coskun, SB
    In this paper, time domain dynamic analysis of dam-reservoir interaction is presented by coupling the dual reciprocity boundary element method in the infinite fluid domain and the finite element method in the solid domain. An efficient coupling procedure is formulated by using sub-structuring method. Sommerfeld's boundary condition for far end of the infinite domain is implemented. To verify the proposed scheme, numerical examples are carried out to compare with the available exact solutions and results of the finite-finite element coupling.

    Time-domain dynamic analysis of dam-reservoir-foundation interaction including the reservoir bottom absorption
    (JOHN WILEY & SONS LTD) Küçükarslan, S
    In this paper, time-domain dynamic analysis of dam-reservoir-foundation interaction is presented by coupling the dual reciprocity boundary element method (DRBEM) in the infinite reservoir and foundation domain and the finite element method in the finite dam domain. An efficient coupling procedure is formulated by using the sub-structuring method. The effects of the reservoir bottom absorption are included in the formulations. Sharan's boundary condition for the far-end of the infinite fluid domain is implemented. To verify the proposed scheme, numerical examples are carried out by comparing with the available exact solutions and finite-finite element coupling results for the dam-reservoir interaction. A complete dam-reservoir-foundation interaction is also studied by including the bottom absorption effects. Copyright (C) 2004 John Wiley Sons, Ltd.

    Transient analysis of dam-reservoir interaction including the reservoir bottom effects
    (ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD) Küçükarslan, S; Coskun, SB; Taskin, B
    In this paper, time-domain transient analysis of elastic dam-reservoir interaction including the reservoir bottom effects is presented by coupling the finite element method in the infinite fluid domain and in the solid domain. An efficient coupling procedure is formulated by a substructuring method. Sommerfeld's boundary condition for the far end of the infinite domain is implemented. To verify the proposed scheme, numerical examples are given to compare with available exact solutions for rigid and elastic dam cases. Finally, a numerical example is studied to evaluate the effects of the reservoir bottom. (c) 2005 Elsevier Ltd. All rights reserved.
