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 ...
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 ...
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 ...
Elastic critical load of plates and plate girders subjected to patch load / Elastična kritična sila ploča i limenih nosača pod dejstvom lokalizovanog opterećenja
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
The determination of the elastic critical load (buckling load) is an important element of the assessment of the ultimate load of plate girders according to Eurocode 3 for design of steel structures. An analysis of the ...
Polyhedral forms obtained by combinig lateral sheet of CP II-10 and truncated dodecahedron / Poliedarske forme nastale spajanjem omotača CP II-10 i zarubljenog dodekaedra
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
The paper analyzes the possibility of obtaining polyhedral shapes formed by combining polyhedral surfaces based on the segment surface of elongated concave pyramids of the second sort (CeP II-10, type A and type B). In ...

(Beograd:University of Belgrade, Faculty of Mechanical Engineering, 2017)
The paper analyzes the possibility of obtaining polyhedral shapes formed by combining polyhedral surfaces based on the segment surface of elongated concave pyramids of the second sort (CeP II-10, type A and type B). In ...
Positional accuracy of geographical information and recent standards for its evaluation / Položajna tačnost geografskih informacija i savremeni standardi za njeno ocenjivanje
(Srpsko geografsko društvo, Beograd, 2011)
Positional accuracy is important quantity element of quality of geographical information in digital as well as in analoguos form. This paper points to importance and necessity of evaluation of positional accuracy in recent ...
Paper strips driven design: Application on doubly curved surfaces / Dizajniranje papirnim trakama - primena na dvostruko zakrivljenim površima
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
In this paper, we address the challenge of overcoming the problem of developing doubly curved surfaces in product design. Product design uses two kinds of surfaces, developable surfaces and non-developable surfaces, which ...
Analysis of the embodied energy and the CO2 emission in construction process of a bridge structure from the aspect of sustainability / Analiza vezane energije i emisije CO2 za izvođenje mostovske konstrukcije sa stanovišta održivosti
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2015)
This paper presents a comparative analysis of embodied energy and CO2 emission, in the construction process of three bridge structures. Analyzed structures are prestressed concrete bridges with different structural systems ...
Calibration of the bolt pretension by strain gauges vs. FEA / Eksperimentalna i numerička kalibracija sile prednaprezanja u visokovrednim zavrtnjevima
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
When applying high strength bolts in friction connections, a load-bearing capacity depends on pretension force in the bolts as well as on friction coefficient found on friction surfaces. It is important to get the reliable ...
