one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
Performance based earthquake engineering approach has been under evolution for seismic safety assessment of structures. Qualitative and quantitative definition of seismic performance levels is major challenge of concrete gravity dams. The main purpose of this article is damage patterns and failure scenarios prediction of structure while they prepare a suitable basement to determine dam seismic ...
seismic behavior of a rockfill dam with asphalt-concrete core has been studied utilizing numerical models with material parameters determined by laboratory tests. the case study selected for these analyses, is the meyjaran asphalt core dam, recently constructed in northern iran, with 60 m height and 180 m crest length. the numerical analyses have been performed using a nonlinear three dimension...
