dc.description.abstract | Beton zbijen valjanjem ('valjani beton' ili 'RCC' - Roller Compacted Concrete) je vrsta betona sa niskim sadržajem cementa koja se često koristi kod betonskih gravitacionih brana. U radu je razmatran prostorni model za neustaljenu faznu termičko- naponsku analizu brana od valjanog betona. Kalibracija i verifikacija modela uređeni su na osnovu terenskih merenja na brani Platanovrisi. Istraživanje je urađeno uzimajući u obzir stvarnu geometriju brane, dinamiku ugradnje RCC-a i stvarne osobine materijala. Rezultati proračuna pokazuju da razvijeni 3D model omogućava pouzdano predviđanje termičkih napona i određivanje rastojanja između razdelnica kod gravitacionih RCC brana. | sr |
dc.description.abstract | Roller Compacted Concrete (RCC) is a special concrete mixture with low cement content, frequently used for concrete gravity dams. This paper deals with the 3D finite element model for unsteady phased thermal-stress analysis of RCC dams. Model calibration and verification has been done, based on the in-situ measurements of the Platanovryssi dam. The study has been done using the actual dam shape, RCC time schedule, and material properties. The results prove that the recommended 3D model enables a reliable thermal-stress prediction and transversal joint distance computation for an RCC gravity dam. | en |
