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 ...
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 ...
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 ...
Local behaviour of the connector with mechanical coupler and rebar anchor under tension load
(Society for Materials and Structures Testing of Serbia; Faculty of Civil Engineering, University of Belgrade, Serbia; Association of Structural Engineers of Serbia, 2023)
In the past few decades, demountable connectors have often been used for
connections in composite and mixed steel-concrete structures to reduce
construction time and costs. Furthermore, the application of demountable
connectors ...
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, ...
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) ...
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. ...
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 ...
Flexural buckling of hot-finished and cold-formed elliptical hollow section columns: Numerical comparative analysis / Fleksiono izvijanje naknadno termički obrađenih i hladnooblikovanih stubova elipsastog poprečnog preseka: Numerička uporedna analiza
(Beograd : Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, 2019)
Even though structural elements of the elliptical hollow section (EHS) have been introduced to the construction market in the past years, the rules for their design were only partially introduced into the suitable codified ...
