Mechanical properties of recycled aggregate concrete / Mehaničke karakteristike betona na bazi recikliranog agregata
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
For the purpose of the environmental preservation and sustainable development, production of concrete made of recycled concrete rubble (recycled aggregate concrete-RAC) become more often. Results of experimental investigations ...
Calibrating and validating a FE model for long-term behavior of RC beams / Kalibracija i verifikacija modela konačnih elemenata za dugotrajno ponašanje AB greda
(Savez inženjera i tehničara Srbije, Beograd, 2014)
This study presents the research carried out in finding an optimal finite element (FE) model for calculating the long-term behavior of reinforced concrete (RC) beams. A multi-purpose finite element software DIANA was used. ...
Modelling the Drina river basin water resources system and analysis of selected development and climate scenarios / Modeliranje vodoprivrednog sistema sliva Drine i analiza izabranih razvojnih i klimatskih scenarija
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2017)
The paper presents the methodological framework for the analysis of the Drina River basin water resources system under different development and climate scenarios. Within this methodological framework, a water management ...
Uporedna analiza betonskog integralnog nadputnjaka pri različitim karakteristikama tla
(Savez inženjera i tehničara Srbije, Beograd, 2022)
U okviru rada razmatran je betonski integralni nadputnjak raspona 30 metara na magistralnom putu koji je fundiran na šipovima. Analiziran je uticaj krutosti tla na vrednosti statičkih uticaja merodavnih za dimenzionisanje ...
An application of Groebner bases to planarity of intersection of surfaces
(Univerzitet u Nišu - Prirodno-matematički fakultet - Departmant za matematiku i informatiku, Niš, 2009)
In this paper we use Groebner bases theory in order to determine planarity of intersections of two algebraic surfaces in R3. We specially considered plane sections of certain type of conoid which has a cubic egg curve as ...
Composite Concave Cupolae as Geometric and Architectural Forms
(Journal for Geometry and Graphics, 2015)
In this paper, the geometry of concave cupolae has been the starting
point for the generation of composite polyhedral structures, usable as formative
patterns for architectural purposes. Obtained by linking paper folding ...
Primena grejnih kablova u izvođenju betonskih radova pri ekstremno niskim temperaturama sa numeričkim primerima
(Udruženje inženjera građevinarstva geotehnike arhitekture i urbanista, 2021)
Očvršćavanje betona u uslovima niskih temperatura dovodi do usporavanja procesa
hidratacije cementa. U ekstremnim uslovima može doći do prekidanja hidratacije cementa i
pojave smrzavanja vode u betonu. Sve to može dovesti ...
The pressurized pipelines: The risk of bidirectional fluid exchange with the environment / Cevovodi pod pritiskom i rizik od razmene fluida sa okolinom
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2009)
The pressurized pipeline fluid transport is supposed to be cheap, reliable and efficient. If buried, pipelines are hard observable by means of leaks, minor cracks and asset damages. These phenomena can influence both the ...
Specific properties of recycled aggregate concrete production technology / Specifičnosti tehnologije spravljanja betona na bazi recikliranog agregata
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
This state-of-the-art paper deals with the differences in production technology of concrete made with recycled aggregate. The properties of recycled aggregate, as a component for new concrete production, are being analyzed ...
The measurement of inclination on gravity concrete dams using the tiltmeter instrument / Merenje nagiba kod gravitacionih betonskih brana primenom instrumenta tiltmetar
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The measurement of inclination on gravity concrete dams using the instrument tiltmeter is described and discussed with special reference on obtained results on the dam 'Đerdap 2' acquired in the three years period. Tiltmetar ...
