the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
Seismic Response of the Kavar Concrete Face Rockfill Dam (RESEARCH NOTE)
This study deals with the dynamic behavior of the kavar concrete Abstract face rockfill damwhich is the first dam of this type to be const ructed in a highly active seismic prone area,situated in the state of Fars southern part of the Islamic Republic of Iran. The finite elementmethod was used as a tool to carry out this study. The finite element discretization was carriedout under plane strain...

15 صفحه اولNon-linear Analysis of Stress and Strain of Concrete-faced Rockfill Dam for Sequential Impoundment Process
The rockfill is modeled as nonlinear elastic material, whose stress-dependent tangent modulus is related to the confining pressure. The parameters of constitutive relationship of stress and strain are determined by tri-dimensional compression test in laboratory. The model applied in this study adopts the technique of element birth and death to simulate the sequential impoundment process of conc...
متن کاملA Dynamic Analysis of the Interaction of Concrete Face and Rockfill Part in Concrete Faced Rockfill Dams
Introduction Concrete faced rockfill dams have been considered in recent years more than other types of dams due to their low dependency on the bed and the shape of the valley, as well as the simpler construction technology. In this regard, rockfill dams are a suitable substitute for embankment dams because of higher stability of the body and the availability of rock aggregates. On the other h...
