The paper deals with the reliability–based design optimization (RBDO) of concrete gravity dams subjected to earthquake load using subset simulation. The optimization problem is formulated such that the optimal shape of concrete gravity dam described by a number of variables is found by minimizing the total cost of concrete gravity dam for the given target reliability. In order to achieve this p...
Dam behavior investigation has been considered for a long time, with many studies conducted to identify and predict factors influencing such structures. In common dynamic analyses of dams, an input acceleration is typically used. At the same time, it was proved that such structures with a large contact with the ground usually experience different accelerations in their various supporting points...
Original scientific paper This paper analyses the seismic strength of the high arch concrete dam of the Hydro-power plant "Piva" on the river Piva in Montenegro, which was built in the seismic active area almost forty years ago. This is the double curve concrete arch dam, 220 m high and it belongs to the group of very high dams, among the highest 25 in the world. Linear and nonlinear analysis w...
This study focuses on the shape optimization of concrete gravity dams considering dam– water–foundation interaction and nonlinear effects subject to earthquake. The concrete gravity dam is considered as a two–dimensional structure involving the geometry and material nonlinearity effects. For the description of the nonlinear behavior of concrete material under earthquake loads, the Drucker–Prage...
