Numerical modelling of concrete-filled steel tube columns under axial compression
(International Congress Proceedings / Association of Structural Engineers of Serbia, 16. Congress, 2022)
The paper presents the numerical modelling of concrete-filled steel tube stub columns under axial compression. The nonlinear 3D finite element model for the analysis was developed using ABAQUS software. The modelling, ...
Long-term behavior of composite concrete girders made continuous
(MASE, 2011)
Time-dependent effects are significant for the design of range of concrete structures. Reliable data for creep and shrinkage properties of concrete and analytical procedures are needed to account for these effects. A number ...

Important aspects in design of anemometric steel masts in the Republic of Serbia
(Association of Structural Engineers of Serbia, 2022)
Design and construction of large wind farms requires preliminary measurement of wind energy potential at the future wind farm location. For these purposes, anemometer steel guyed masts are used, which carry equipment for ...
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 ...
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 ...
