Free vibration analysis of stiffened and cracked laminated composite plate assemblies using shear-deformable dynamic stiffness elements
(Elsevier Ltd, 2017)
In the paper, the dynamic stiffness method based on the HSDT and FSDT plate theories is applied to study free vibration characteristics of composite stiffened and cracked plate assemblies. The dynamic stiffness matrices ...
Geotehnički uslovi sanacije Doma Narodne skupštine u Beogradu
(Savez građevinskih inženjera Srbije, 2011)
Dom Narodne Skupštine je jedan od naših najznačajnijih spomenika kulture, na kome su uočena brojna oštećenja pojedinih elemenata konstrukcije i koji, po sadašnjim propisima, ne ispunjava uslove potrebne za dinamičku ...
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 ...
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 ...
