On the properties of the concave antiprisms of second sort / O osobinama konkavnih antiprizmi druge vrste
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2013)
The paper examines geometrical, static and dynamic properties of the polyhedral structures obtained by folding and creasing the two-rowed segment of equilateral triangular net. Bases of these concave polyhedra are regular, ...
The pencil of the 4th and 3rd order surfaces obtained as a harmonic equivalent of the pencil of quadrics through a 4th order space curve of the 1st category / Pramen površi 4. i 3. reda dobijen kao harmonijski ekvivalent pramena kvadrika kroz prostornu krivu 4. reda 1. vrste
(Univerzitet u Nišu, Niš, 2012)
This paper shows the process of inverting the 4th ordered space curve of the first category with a self-intersecting point (with two planes of symmetry) and determining its harmonic equivalent. There are harmonic equivalents ...
Numerical analysis of flexural buckling resistance of non-uniform compression members / Numerička analiza nosivosti neuniformnih pritisnutih elemenata na fleksiono izvijanje
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
This paper presents parametric linear-elastic analysis of flexural buckling of idealised non-uniform member and nonlinear analysis of flexural buckling with equivalent imperfections, using software package Abaqus. The ...
Distribution of chromium, nickel, copper and zinc in the Al Zintan area, northwestern Libya
(Geološki anali Balkanskoga poluostrva, 2018)
Global population is growing rapidly. As a result, increasingly large areas are being settled and farmed. This devastates soils and causes pollution by heavy metals and other components. Heavy metals in the environment ...
Experimental testing of reinforced end-notched glulam beams / Eksperimentalno ispitivanje ojačanih lepljeno lameliranih drvenih nosača sa redukovanom visinom preseka
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
Notches made at the ends of timber beams significantly decrease load carrying capacity of a structural member. This paper presents an experimental research on bending behaviour of end-notched glulam beams, with and without ...
Bridge Deck Runoff Water Quality Modeling - The "Gazela" Bridge Case Study
(Water Research and Management, 2018)
Environmental assessment of copper slag aggregate concrete
(DIMK. DGKS i Građevinski fakultet Univerziteta u Beogradu, 2022)
Due to the extremely large global production and utilization of concrete, the concrete
industry is considered a large consumer of energy and natural resources and one
of the main sources of greenhouse emissions and waste ...
Influence of cement replacement with limestone filler on the properties of concrete
(Građevinski materijali i konstrukcije, 2021)
This paper presents an experimental research of one type of green concrete in which Portland cement was replaced with two types of limestone filler of the same origin and mineralogical composition, but with a different ...
Statistical analysis of concrete quality testing results / Statistička analiza rezultata ispitivanja kvaliteta betona
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
This paper statistically investigates the testing results of compressive strength and density of control concrete specimens tested in the Laboratory for materials, Faculty of Civil Engineering, University of Belgrade, ...
Properties modeling of cement composites made of fly ash / Modelovanje svojstava maltera primenom elektro-filterskog pepela
(Inženjersko društvo za koroziju, Beograd, 2014)
There is a number of advantages when using fly ash in cement composites. Fly ash is known for decades for its' pozzolanic properties, and thus it is mostly used as an mineral admixture in the process of production of cement. ...
