dc.description.abstractUpstream cutoff in the concrete gravity dam foundation is introduced as a general stability measure in the beginning of the 20-th century. It become widely accepted in design practice in the late 50-ties. Nevertheless, very little is done in the stress evaluation in the cutoff zone, so far. The intention of this research is to obtain a reliable assessment of the stresses in this zone, particularly occurrence and distribution of tensile stresses, which may produce cracks. The research is based on a finite-element model, with special features in the foundation zone, and encompassed large range of dam heights, cutoff shapes, and foundation properties.en
dc.description.abstractKao mera opšte stabilnosti kod gravitacionih betonskih brana, uzvodni zub je prvi put primenjen početkom 20. veka, dok se sa njegovom širom primenom otpočelo pedesetak godina kasnije. Međutim, do sada nije posvećena dužna pažnja proceni naponskog stanja u oblasti uzvodnog zuba. Cilj istraživanja je da se dobije pouzdana procena napona u ovoj zoni, sa posebnim osvrtom na napone zatezanja, koji mogu da izazovu prsline u betonu. Istraživanje je zasnovano na metodi konačnih elemenata, sa originalnim rešenjem za temeljnu spojnicu. Parametarskom analizom je obuhvaćen širok opseg visina brana, oblika uzvodnog zuba i karakteristika temelja.sr
