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 ...
Efficient Adaptive Section Discretization Schemes
(Conference: Third European Conference on Earthquake Engineering and Seismology, 2022)
The paper summarises a family of adaptive fiber section discretization schemesfor nonlinear frame elements. The proposed schemes use cubature integration rules forintegration within the linear-elastic part of a section and ...
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 ...
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, ...
Nonlinear stability analysis of the frame structures / Nelinearna analiza stabilnosti okvirnih nosača
