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 ...
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 ...
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 ...
Supercritical flow in circular pipe bends / Burno tečenje u krivini kružne cevi
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
In this paper a complex flow pattern occurring in a closed conduit bend with supercritical flow is analyzed. The research was done by a scale (physical hydraulic) model, and a numerical model developed in Ansys (Fluent) ...
Redistribution of internal forces in composite concrete girders made continuous vs. time / Preraspodela uticaja kod naknadno kontinuiranih spregnutih armiranobetonskih nosača tokom vremena
(Univerzitet u Nišu, Niš, 2011)
Research on the long-term behavior of composite concrete girders made continuous is presented in the paper. Concrete precast element is cracked under construction load. Creep and differential shrinkage of precast and in-situ ...
Vibrations of composite steel-concrete floors induced by human activities / Vibracije spregnutih nosača međuspratnih konstrukcija od čelika i betona, izazvanih aktivnostima ljudi
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
The latest demands in construction design towards slender structures with large spans, large open interiors, unconventional shapes and constructional solutions are leading to the extensive problems related to the serviceability ...
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, ...
Simple analysis of daylight saving time effects in Belgrade climate and latitude
(Institut za arhitekturu i urbanizam Srbije, Beograd, 2018)
Contemporary controversy about daylight saving time (DST) is mainly derived from different standpoints in studies investigating the positive and negative effects of the clock shift during summer period. From the standpoint ...
