Estimation of ultimate strength of slender ccfst columns using artificial neural networks
(16th Congress of Association of Structural Engineers of Serbia, 2022)
This paper proposes the use of artificial neural network (ANN) algorithms to estimate the ultimate compressive strength of slender circular concrete-filled steel tubular (CCFST) columns. A dataset of 1051 samples was applied ...
Slobodne vibracije rotaciono-simetričnih sistema primenom metode dinamičke krutosti / Free vibration study of axisymmetric assemblies using dynamic stiffness method
(Univerzitet u Beogradu Građevinski fakultet BeogradDruštvo građevinskih konstruktera Srbije, 2022)
U ovom radu primenjena je metoda dinamičke krutosti za analizu slobodnih vibracija sistema koji se sastoji od kružne cilindrične ljuske i kružnih i/ili prstenastih ploča. Pri formulaciji dinamičkih matrica krutosti korišćena ...
Progressive failure analysis of composite laminates loaded in compression / Анализа прогресивног лома композитних ламината изложених сили притиска
(Univerzitet u Beogradu Građevinski fakultet BeogradDruštvo građevinskih konstruktera Srbije, 2022)
U ovom radu sprovedena je analiza progresivnog loma pločastih kompozitnih laminata,
opterećenih na pritisak. Hashin-ov kriterijum je korišćen prilikom određivanja inicijacije loma
laminata, dok je razvoj oštećenja ...
Elastic critical load of longitudinally unstiffened I-girders subjected to patch loading
(Association of Structural Engineers of Serbia, 2022)
The paper considers the elastic critical load of longitudinally unstiffened I-girders subjected to a localized load of variable length in the plane of the web. In the current regulations, the contribution of the patch ...
Influence of stiffener and flange on elastic critical load of i-girders subjected to patch loading
(MASE Macedonian Association of Structural Engineering, 2022)
The paper considers the influence of patch load length, flange thickness, and stiffener's characteristics
on the behaviour of steel plate girders subjected to patch loading in terms of elastic stability. The aim is
to ...
Composite Steel-Concrete Beam Analysis using Different Methods
(Univerzitet u Beogradu Građevinski fakultetDruštvo građevinskih konstruktera Srbije, 2021)
The paper compares the following methods for analysis of composite steel-concrete beams: the
“exact” analysis method, simplified method, effective modulus method and the method proposed
by Eurocode 4 design code. The ...
A model for the analysis of elasto-plastic buckling of compressed columns
(8th International Congress of Serbian Society of Mechanics Kragujevac, Serbia, June 28-30, 2021, 224-231-, 2021)
Modern structures often use new technology materials as special high-strength steels. This is
one of the reasons why cross-sections of structural members are smaller and structures are lighter
than those built fifty years ...
Free vibrations of FGM plates with imperfections using layerwise finite element
(Mathematical Institute SANU, Belgrade, Serbia, 2022)
The initial geometrical imperfections, as deviations between the actual and intended shape, are in most cases randomly distributed in real structures and their real shape is not known in advance. Most of the studies reported ...
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 ...
Software for calculation of pedestrian-induced vibration of floors / Softver za proračun vibracija međuspratnih konstrukcija usled dinamičke sile pešaka
(Association of Structural Engineers of Serbia, 2022)
Trends in contemporary architecture towards open-plan spaces in commercial and residential
buildings have created problems with excessive vibrations of large-span floors induced by active
people. Solving vibration ...
