elevated water tanks as one of the main lifeline elements are the structures of high importance. since they are extremely vulnerable under lateral forces, their serviceability performance during and after strong earthquakes is a matter of concern. as such, in recent years, the seismic behavior of water tanks has been the focus of a significant amount of studies. in the present work, three reinf...

elevated tanks are very important structures and consist of various types. water supply is vital to control fires during earthquakes. also they are utilized to store different products, like petroleum supplies in cities and industrial zones. damage to these structures during strong ground motions may lead to fire or other hazardous events. elevated tanks should stay functional after and before ...

in this study, the effective parameters on the inelastic response of asymmetric buildings is evaluated for an ensemble of real iranian earthquake records by considering soil-structure interaction. then, the design eccentricity obtained from the inelastic dynamic soil-structure analysis is compared with the design eccentricity of seisimic codes of iran, atc-3, new zeland, canada, mexico, austral...

In this paper, mortality in the immediate aftermath of an earthquake is studied on a worldwide scale using multivariate analysis. A statistical method is presented that analyzes reported earthquake fatalities as a function of a heterogeneous set of parameters selected on the basis of their presumed influence on earthquake mortality. The ensemble was compiled from demographic, seismic, and repor...

A recently developed nonstationary stochastic model of strong earthquake ground motion is described. The model employs filtering of a white-noise process, where nonstationarity is achieved by modulating the intensity and varying the filter parameters in time. The model is fitted to a target accelerogram by matching a set of statistical measures that characterize the evolution of the intensity, ...

The 2011 off the Pacific coast of Tohoku earthquake (Mw9.0), which produced many strong motion records, provides an opportunity to examine the characteristics of strong ground motion from a gigantic earthquake. In this paper, the preliminary analysis of the ground motion attenuation, spectral shape and duration was performed using the selected strong motion records of the earthquake. The result...
