Određivanje in-situ koeficijenta trenja i imperfekcije kablova za prednaprezanje / Determination of the in situ coefficient of friction and imperfection of prestressing cables
(Građevinski materijali i konstrukcije, 2017)
Prestressing structural elements allows an increase in the spans of reinforced concrete structures. In the design and dimensioning of prestressed reinforced concrete structures it is necessary to know, that is to adopt a ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
