Water storage tanks not designed explicitly for seismic loading could require retrofit. One of the common ways of retrofit include some structural change in the lateral load resisting system that could be expensive and requires the tank to be out of service for relatively long time. This paper introduces a novel method to reduce seismic demand on tank’s wall without structural intervention. Thi...

This paper aims to first present a review of studies on numerical modeling and seismic response analysis above ground steel liquid storage tanks. On that basis, procedure for estimating dynamic parameters associated with simplified models anchored unanchored conditions together calculation methods responses damage states tanks are presented. In which, the nonlinear behavior bottom plate in case...

during recent years oil products has decreased because of growing population and increasing demand to oil products and decreasing of crude oil extraction at compare to export. however, to achieve suitable levels of production, the use of improved technologies should be considered. another way to prevent the evaporation and leakage from oil storage tanks and their products are using of storage t...

This paper deals with the seismic column design of 35 elevated RC water storage tanks. Tanks comprise a top conic trunk reservoir, variable hollow square cross-sections, and shallow foundation on sand layer. The five-column heights considered are 20, 25, 30, 35, 40 m. five tanks subjected to seven degrees loading characterized by reference peak ground acceleration in Eurocode 8. designed agains...

Ground water nitrate concentrations on Nantucket Island, Massachusetts, were analyzed to assess the effects of land use on ground water quality. Exploratory data analysis was applied to historic ground water nitrate concentrations to determine spatial and temporal trends. Maximum likelihood Tobit and logistic regression analyses of explanatory variables that characterize land use within a 1000-...
