Damage estimation on concrete gravity dams through artificial accelerograms

open access: yesMATEC Web of Conferences, 2018
The aim of this paper is to analyse the damage on gravity dams through artificial earthquakes from two methods. The first procedure defines the performance and the response curve of concrete gravity dams using a harmonic function which establishes linear

НОРМИРОВАННОЕ УСКОРЕНИЕ СПЕКТРА РЕАКЦИИ ДЛЯ ГОРОДА ТБИЛИСИ С УЧЕТОМ СЕЙСМОЛОГИЧЕСКИХ ПАРАМЕТРОВ И ВЛИЯНИЯ ГРУНТОВЫХ УСЛОВИЙ

open access: yesГеология и геофизика Юга России, 2014
Из-за отсутствия реальных записей сильных движений целью данного исследования является разработка методологии для быстрой генерации горизонтальных и вертикальных составляющих грунтовых движений землетрясения на любом участке для города Тбилиси.

A model for the shape of the Fourier amplitude spectrum of acceleration at high frequencies [PDF]

open access: yes, 1984
At high frequencies f the spectrum of S-wave accelerations is characterized by a trend of exponential decay, e^(−πkf). In our study, the spectral decay parameter k shows little variation at a single station for multiple earthquakes at the same distances,

Seismic hazard versus design accelerograms

open access: yesConstructii: Journal of Civil Engineering Research, 2012
The developments presented herewith arise from the legitimate wish and task of structural engineers of performing consistent analyses of risk and safety for works located in seismic regions. The paper adopts a probabilistic viewpoint, or philosophy. The starting point of this discussion is based on well – established approaches, while at the same time ...

An array of strong-motion accelerographs in Bear Valley, California [PDF]

open access: yes, 1975
Fifteen strong-motion accelerographs, each with the capability of writing the WWVB absolute time code on the recorded accelerogram, have been deployed in an elliptical array, at a station spacing of several kilometers, along the San Andreas Fault in the ...

Spatial variation of ground motion determined from accelerograms recorded on a highway bridge [PDF]

open access: yes, 1985
A set of time-synchronized strong-motion accelerograms, obtained on the San Juan Bautista 156/101 Separation Bridge in California during the 6 August 1979 Coyote Lake earthquake (M_L = 5.9), are used to study the spatial variation of ground motion at the
