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 ...
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 ...
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 ...
Behaviour of thin-walled cylindrical and conical shells: Carbon vs. stainless steel / Poređenje ponašanja tankih cilindričnih i konusnih ljuski od ugljeničnog i nerđajućeg čelika
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2019)
