This paper deals with the ambient vibration tests performed in an arch dam in two different working conditions in order to assess the effect produced by two different reservoir water levels on the structural vibration properties. The study consists of an experimental part and a numerical part. The experimental tests were carried out in two different periods of the year, at the beginning of autu...

This paper presents an applicable and practical computer program(ODPSAD) and suggests a new algorithm for geometry of concrete arch dams. In this program shape optimization of arch dams for static and dynamic loads and enhancement of its seismic behaviour is carried out. abutment excavation and dam body volumes have been considered as the objective function and in order to increase the consiste...

In this paper, Endurance Time Analysis (ETA) method which is a new time-history based dynamic pushover procedure is introduced and its application in linear analysis of concrete arch dams is investigated. In this method the structure is subjected to gradually intensifying acceleration functions and its performance is evaluated based on the length of the time duration that can satisfy required p...

In the present paper, a 3D numerical model has been applied to predict the flow hydrodynamics around power intakes within the Dez dam reservoir. The Dez dam is a 203 m high, double arch concrete dam which is constructed by Italians in 1962. Since then, sedimentation in reservoirhas continued and since the dam does not have bottom outlet, the reservoir bed level is raising by a rate of about 2.5...

The seismic safety assessment of large concrete dams remains a significant challenge in dam engineering, as it requires appropriate analysis methods, modern performance criteria, and advanced numerical models to simulate the behavior. This paper presents method for arch based on Endurance Time Analysis (ETA), using tensile compressive damage results from robust formulation considering joint ope...
