Seismic analysis of Fractured Koyna Concrete Gravity Dam

Abstract: Seismic analysis of a fractured dam is a generally complex problem. This paper presents an earthquake behavior investigation of a fractured concrete gravity dam considering dam-reservoir--foundation rock interaction. The Koyna dam profile, located in India, is adopted in this study. The nonlinear finite element analyses are conducted taking into account empty and full reservoir cases, to exhibit the hydrodynamic e ect of reservoir water on the dam earthquake response. The hydrodynamic pressure is modeled by fl… Show more
