An analysis method is presented for the transient linear or nonlinear analysis of earthquake responses of concrete gravity dams considering the effects of the dynamic interactions between flexible dam body and reservoir impounding compressible water under earthquake loadings. The dam body is modeled with linear and/or nonlinear finite elements. The far field of the reservoir is formulated as a displacement-based transmitting boundary in frequency domain that can radiate energy into infinity. Then the transmitting boundary is transformed for the direct coupling in time domain. The near-field region is modeled as compressible fluid contained between two substructures. The substructure method is applied to a nonlinear analysis of a concrete gravity dam. The results show the location and severity of damages demonstrating the applicability to the seismic evaluation of existing and new dams. |
