چکیده
In this paper, we consider the optimization of temperature conditions and thermo-stressed state a concrete gravity dam made extra lean roller-compacted constructed in climate corresponding to Pskem HPP Republic Uzbekistan. We show need take into account effect solar radiation on heating mass during layer-by-layer construction dam. A methodology was used estimate radiation, considering cloud cover use field satellite observations. The seasonality work terrain surrounding site were also examined. assessed degree influence factors acting formation regime using factor experiment technique. Regression equations, which allowed us values thermal stress arising structure period, obtained. created numerical model has been for estimation option low-cement concrete. On basis calculations stress–strain elastic elastic-plastic formulations, possible cracking evaluated. competitiveness considered with ground one is shown.

Investigation of Nonlinear Behavior of Material on Seismic Performance of Roller Compacted Concrete Dam
In this research, the effect of nonlinear behavior of concrete on seismic performance of roller compacted concrete (RCC) is discussed. Nonlinear behavior of material shows the behavior close to reality due to use of all structural capacity and it is considered the most appropriate method for design. So in this paper, by using the appropriate definition of nonlinear behavior of RCC, the Ansys so...
متن کاملPredicting the deformation of roller compacted concrete dam using least squares support vector machine
As a new type of dam, roller compacted concrete dam (RCCD) develops very fast in recent years. Deformation plays an important role in the RCCD’s safety. The deformation of RCCD is influenced mainly by three parts: water pressure, temperature and time effect. As to any of the three parts, there are many factors. Therefore, the deformation of RCCD is a complicated system. The least squares suppor...

متن کاملInvestigating the Effect of natural Pozzolans on Mechanical Properties of Roller Compacted Concrete
Roller Compacted Concrete (RCC), is a concrete with zero slump, which is used in damming and road pavement. Roller Compacted Concrete Pavement (RCCP) bear heavy traffic loads and severe weather conditions. This type of concrete is due to its economic and environmental capabilities, including reduced construction and maintenance costs, longer durability and longer lifetime, as well as environmen...
