On the Wind Energy Resource above High-Rise Buildings
(MDPI, 2020)
One of the main challenges of urban wind energy harvesting is the understanding of the flow characteristics where urban wind turbines are to be installed. Among viable locations within the urban environment, high-rise ...
Pravilne konkavne kupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
The term cupola stands for a polyhedron consisting of two regular polygons: n-gon and 2n-gon in parallel planes, connected by an alternating series of squares and equilateral triangles, ie. Johnsonsolids J3, J4 and J5. ...
Zlatni presek i pravilne konkavne bikupole druge vrste
(Novi Sad: Fakultet tehničkih nauka, 2006)
Zlatni presek (racio) predstavlja odnos između strane pravilnog pentagona i njegove dijagonale, a takođe se dovodi u vezu sa susednim članovima Fibonacijevog niza. Istraživaem i upoređivanjem metričkih parametara konkavnih ...
Multilayer Plate Finite Element / Konačni element višeslojne laminatne ploče
(Faculty of Civil Engineering of the University of Belgrade─Chair for Technical Mechanics and Theory of structuresGrađevinski fakultet Univerziteta u Beogradu─Katedra za Tehničku mehaniku i teoriju konstrukcija, 2009)
Under the manufacturing and service conditions, laminated composites are exposed to various damage modes, on the local or ply level. As 2D plate models are capable only to determine global behaviour of laminated composites, ...
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 ...
Вибрације и избочавањe плоча и љуски применом методе динамичке крутости
(Универзитет у Београду, Грађевински факултет, 2016)
Метод динамичке крутости (МДК) представља алтернативу методуконачних елемената (МКЕ) у анализи вибрација и избочавањаконструкција. Основни елемент у МДК је континуални елемент, односноњегова матрица крутости, која је ...
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 ...
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 modal analysis of cross-laminated timber floors
(EURODYN 2023, XII International Conference on Structural Dynamics, 02-05 July 2023, Delft, The Netherlands, 2023)
Cross-laminated timber (CLT) floors have gained in popularity due to their outstanding strength,
aesthetic appeal, good fire resistance, and high level of prefabrication. However, due to their
high stiffness-to-weight ...
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 ...
