Izogeometrijski pristup u analizi slobodnih vibracija prostornih Bernuli – Ojlerovih grednih nosača
(2019)
У овом раду приказана је анализа слободних вибрација просторних гредних Бернули – Ојлерових носача произвољног облика применом изогеометријског приступа. Изогеометријским приступом геометрија носача се описује на исти начин ...
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 ...
Perception of three-dimensional geometric shapes as virtual 3D road markings
(Serbian Society for Geometry and Graphics Faculty of Technical Sciences, University of Novi Sad, Belgrade ; Novi Sad, 2018)
Excessive speed and poor driver perception are the causes of a large number of traffic accident. Analysis of the influence of geometry in driver behavior has been widely performed by different researchers. One way to improve ...

(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 ...
An Adaptive Fiber Section Discretization Scheme for Nonlinear Frame Analysis
(American Society of Civil Engineers, 2022)
The paper proposes an adaptive fiber section discretization scheme for inelastic frame elements. The scheme uses cubature rules for the efficient and accurate evaluation of the section response over the elastic portion of ...
Benefits of green roof installations on buildings with flat roof
(Association of Structural Engineers of Serbia, 2022)
In this paper, different aspects of a green roof installation are analyzed on several typical
buildings in Belgrade. The analysis is performed for buildings with extensive and intensive green
roofs. The goal was to ...
Shadow shapes of metamorphoses hypercube
(Serbian Association for Geometry and Graphics; Faculty of Civil Engineering, University of Belgrade; Akademska misao, Belgrade, 2016)
Constructing the Egg Curves Using the Golden Ratio of Pentagon
(Belgrade: Faculty of Architecture in Belgrade; Serbian Society for Geometry and Graphics (SUGIG), 2010)
In the paper it is considered a construction of an egg curve
obtained by continual joining of the circular arcs with three different
centers. These three centers form sharp or flat triangles of the
pentagon (sharp and ...
Konstruktivni postupci u prostornim transformacijama površi jednogranog eliptičkog hiperboloida / The Constructive procedures in the spatial transformations of the surface elliptical hyperboloid of one sheet
(Универзитет у Београду, Архитектонски факултет, 2013)
Једнограни елиптички хиперболоид (ЈЕХ) је најопштији случај површи двоструке закривљености, из породице правоизводних површи, која настаје клизањем једне трансверзале–генератрисе, дуж три директрисе – мимоилазне праве ...
The role of descriptive geometry in contemporary 3D modeling of cultural heritage objects
(Central Institute for Conservation ; Scientific Association for the Development and Promotion of New Technologies, Belgrade ; Sopot, 2017)
Contemporary graphic design is necessity in each area of cultural heritage research. However, descriptive geometry procedures are substantial and irreplaceable tool for precise construction and presentation of 3D models ...
