Computation of flow separations from bridge girders and effects on flutter derivatives
(Meteorological Institute, CEN, University of Hamburg, Hamburg, 2014)
The widely used formulation of aeroelastic forces presented in the work of Scanlan and Tomko (1971) relies on the frequency dependent coefficients - flutter derivatives and wind tunnel experiments as their identification ...
Accuracy Evaluation of Creep and Shrinkage Calculation Methods According to EC4
(4th International Conference Civil Engineering Science and Practice, Zabljak, 20. 2. 2012, 2012)
In the paper, the creep and shrinkage calculation methods for composite steel-concrete
beams are presented. The approximate methods AAEM, EM and methods according to
Eurocode 4, as well as, the exact method based on the ...
Analysis of Traffic Induced Building Vibrations Using Spectral Element Method
(Third Serbian (28th Yu) Congress on Theoretical and Applied Mechanics, 2011)
In this paper, the effects of traffic induced ground vibrations on the three frame buildings of different
height are analyzed. The structures are subjected to horizontal and vertical ground vibrations which were measured
in ...
Concave Pyramids of Second Sort -The Occurrence, Types, Variations
(Faculty of Civil Engineering and Architecture ; Serbian Society for Geometry and Graphics SUGIG, Niš ; Beograd, 2014)
Correspondingly to the method of generating the Concave Cupolae of second sort, the Concave Pyramids of second sort have the similar logic of origination, and their counterpart in regular faced convex pyramids (tetrahedron, ...
Effects of Creep and Shrinkage on Deflections of Continuous Composite Beams
(Proceedings of Abstracts IConSSM 2011, The 3rd International Congress of Serbian Society of Mechanics, Vlasina lake, Serbia, 5-8 July 2011, 2011)
Creep and shrinkage of concrete affect the behavior of steel-concrete composite
beams and should be taken into account in the analysis of these structures. A number of
methods which have different level of accuracy are ...
Experimental investigation of interference effect of high-rise buildings for wind energy extraction
(Workshop: Tends and Challenges for Wind Energy Harvesting, 2015)
In order to increase wind energy harvesting from urban environment, the wind be- havior and the effect of the surrounding buildings needs to be fully understood. In this paper, wind tunnel experiments of the flow around a ...
Resistance of Composite Column to Compression and Bending
(Proceedings of the 14th International Symposium of MASE, Struga, Makedonija, 28. septembar 2018, 2011)
Design of the composite steel-concrete columns subjected to compression and bending, according to Eurocode
4, is shown in the paper. The effects of imperfections in the axial compression are taken into account
indirectly ...
The Stiffness Matrix of the Fixed-End Composite Frame Element
(The 4th International Congress of Serbian Society of Mechanics, Vrnjacka Banja, Serbia, 4th June 2013, 2013)
The displacement method of frame analysis involves determination of the
element stiffness matrix. In the paper, the stiffness matrix of the fixed-end composite frame
element (type “k”) is derived. In general, the composite ...
