Frequency- and time-domain methods related to flutter instability problem / Metode analize flatera u frekventnom i vremenskom domenu
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Bridge flutter phenomenon presents an important criterion of instability, which should be considered in the bridge design phase. This paper presents different bridge flutter methods which can be used to solve the flutter ...
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 ...
Strengthening of timber beams using FRP bars / Ojačanje drvenih greda primenom FRP šipki
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
The growing need for the reinforcement of timber beams (required due to deterioration or damage to the material or change of use) has led to the development of new methods of reinforcement with modern materials. In the ...
Thermal-stress behaviour of RCC gravity dams / Termičko naponsko stanje gravitacionih brana od valjanog betona
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2015)
Roller Compacted Concrete (RCC) is a special concrete mixture with low cement content, frequently used for concrete gravity dams. This paper deals with the 3D finite element model for unsteady phased thermal-stress analysis ...
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. ...
Railway bridges on interoperable lines: Aspect of track/bridge interaction / Železnički mostovi na interoperabilnim prugama - aspekt interakcije kolosek/most
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
The Institute for Standardization of Serbia has adopted a large number of en standards in the field of bridges as Serbian standards. Unfortunately, technical regulations based on the implementation of the adopted en standards ...
Stepped spillway flow: Comparison of numerical and scale models / Strujanje u stepenastom brzotoku - poređenje rezultata fizičkog i numeričkog modela
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2014)
This paper deals with flow modelling of the stepped spillway for the Bogovina dam. The analysis was conducted using three approaches: scalemodelling, empirical equations and numerical modelling. An acceptable agreement was ...
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 ...
Corrosion of cannon 75/27, model 1911. déport, from the collection of the Military Museum in Belgrade / Korozija topa 75/27, model 1911. deport iz kolekcije Vojnog muzeja u Beogradu
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2012)
This paper analyzes the state of the French Cannon 75/27 model 1911. Déport made of steel. The amount of non-corroded materials, the presence of cracks and other defects in the cannon were determined by the radiographic ...
