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...

A dam may be damaged by occasional extreme loads such as major earthquakes or terrorist attacks during its service. According to the needs of emergency assessment, this paper studies a rapid damage identification method for location and degree in concrete arch dams which is based on dynamic characteristics data, using wavelet transform, packet decomposition, BP neural network D-S evidence theor...
