Seismic Response Prediction of Concrete Arch Dam
The performance evaluation of concrete arch dam under dynamic excitation is a challenging task which requires the comprehensive knowledge of modeling aspects. This paper summarizes important and critical parameters to be considered during dynamic analysis of concrete arch dams. A comprehensive review work is carried out in order to identify the factors

SEISMIC ANALYIS OF CONCRETE ARCH DAMS - TWO CASE STUDIES [PDF]
In the framework of the Portuguese National Programme for Dams with High Hy- droelectric Potential (PNBEPH), a set of large concrete dams is currently under design or construction, including several 100 m high arch dams. Earthquake loading is one of the im- portant aspects to be considered in the design of these structures.
