EARTHQUAKE RESPONSE OF CONCRETE GRAVITY DAMS BY COMBINATION OF FINITE ELEMENT AND BOUNDARY INTEGRAL FORMULATIONS

摘要

Dynamic analysis of concrete gravity dams in the frequency domain is approached by a combination of different numerical techniques. In this method, the dam body is discretized by finite elements, the water region by a semi-infinite fluid hyperelement, and the foundation rock domain by quadratic boundary elements. A new computer program called "MAP-76" is developed based on this method, and the results for an idealized triangular dam are compared with previous available results from accuracy point of view.
