✦ Synopsis

One of the most famous and studied cases of dams subjected to earthquake loading is the Koyna Dam in India. In this study, a two-dimensional model of Koyna Dam at scale was used on a shake table to simulate e!ects and serve as data for non-linear computer model calibration. A new concrete mix was designed for the non-linear similitude modelling. This new mix provided the correct kinematic failure of concrete at scale. Two models were tested to failure: one with an initial shrinkage crack and one monolith. Reservoir e!ects were not modelled. The results of both models are discussed and compared. The ability to model non-linear e!ects is discussed.
