EFFECT OF STRUCTURE-FOUNDATION INTERACTION ON THE DYNAMIC RESPONSE OF DAMS
|
´˜^i‰pjF
Based on the analytic solution of impedance functions of viscoelastic layered medium obtained by the authors, the structure-foundation interaction effect on vibration characteristics and seismic response of dam-foundation system was investigated. Some conclusions have been drawn. A time domain numerical recurrence integration scheme for practical application in interaction analysis is presented, which accounts for the energy dissipation through radiation damping and the spatial variation of soil properties in the foundation medium.
