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 ...
Fiber element formulation for inelastic frame analysis / Formulacija fiber elementa prilikom nelinearne analize ramova
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
The paper discusses two formulations for the fiber based distributed plasticity beam/column element. For force based and displacement based formulations, basic details and main differences are emphasized. The differences ...
Nonlinear stability analysis of the frame structures / Nelinearna analiza stabilnosti okvirnih nosača
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2016)
In this paper the phenomenon of instability of frames in elasto-plastic domain was investigated. Numerical analysis was performed by the finite element method. Stiffness matrices were derived using the trigonometric shape ...
Lateral capacity and deformations of vertical piles loaded by horizontal forces / Bočna nosivost i pomeranja vertikalnih šipova opterećenih horizontalnim silama
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2018)
Pile foundations are frequently loaded by horizontal forces. In such cases, it is important to calculate lateral capacity of vertical piles. It is governed by the strength of the surrounding soil i.e. geotechnical capacity ...
Mechanical rebar splicing / Mehaničko nastavljanje armature
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2014)
Different mechanical rebar splicing systems are presented, and design situations where mechanical splicing has advantage over reinforcement splicing by overlapping and welding are defined in this paper. New international ...
Fiber finite element in nonlinear analysis of square CFT columns / Fiber konačni element u nelinearnoj analizi kvadratnih spregnutih CFT stubova
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
The paper presents nonlinear analysis of square CFT columns using distributed plasticity fiber elements. Behaviour of CFT columns is nonlinear and it is necessary to include different nonlinear effects into the numerical ...
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 ...
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 ...
