Numerical modelling of concrete-filled steel tubular short columns under axial compression
(Building Materials and Structures, 2023)
The paper presents three-dimensional numerical models of short concrete-filled
steel tubular circular columns that can successfully describe the column behaviour
under axial compression. Several of the most commonly used ...
Assessment of water resources system resilience under hazardous events using system dynamic approach and artificial neural networks
(IWA Publishing, 2023)
The objective of this research is to propose a novel framework for assessing the consequences of hazardous events on a water resources system using dynamic resilience. Two types of hazardous events were considered: a severe ...
Stability Calculation of the Plane Steel Frame Structures Using Tangent Modulus Theory
(Hindawi, 2023)
This paper considers the phenomenon of the instability of steel plane frame structures in the elastic-plastic domain. The numerical analysis uses FEM, where the corresponding stiffness matrices are based upon the trigonometric ...
Potential and benefit of green roof energy renovation of existing residential buildings with a flat roof in Belgrade
(Applied Sciences, MDPI, 2023)
This paper considers the phenomenon of the instability of steel plane frame structures in the elastic-plastic domain. The numerical analysis uses FEM, where the corresponding stiffness matrices are based upon the trigonometric ...
Kontrola produktivnosti na građevinskim projekatima zasnovana na ključnim resursima
(16. međunarodna naučna konferencija ''Planiranje, projektovanje, izvođenje i obnova graditeljstva INDiS 2023'', 2023, 2023)
Produktivnost predstavlja jedan od ključnih indikatora građevinske proizvodnje, kao i
faktor koji bitno utiče na visinu nepotrebnih troškova. Unapređenjem produktivnosti
stvaraju se preduslovi za smanjenje proizvodne ...
Determination of ionospheric models using global navigational satellite systems and Bernese GNSS software
(Faculty of Civil Engineering, University of BelgradeInstitute of Physics Belgrade, University of Belgrade, 2023)
Since the last few decades of the 20th and the beginning of civilian application of NAVigation Satellite Timing And Ranging Global Positioning System (NAVSTAR GPS) established by the United States Department of Defense, ...
Experimental investigation of influence parameters on cartridge fired pin resistance
(Ernst & Sohn GmbH, 2023)
Cartridge fired pins, also known as powder actuated fasteners, have a wide application in different construction industry fields, mostly for joints of cold-formed structural elements and profiled steel sheeting, or for ...
With the Chebyshev polynomials through geometric circulant matrices
(XIII Symposium MATHEMATICS AND APPLICATION, Faculty of Mathematics, University of Belgrade, 1-2 December, 2023, 2023)
We will present estimates for spectral norm bounds of the geometric circulant matrices whose entries are the Chebyshev polynomials of the first and the second kind. Some of the obtained results were verified by applying ...
Mixed Spearman’s Correlation Suitability for Sine-Shaped Independent Variables in Natural Sciences
(Institute of Electrical and Electronics Engineers Inc, 2023)
Pearson’s and Spearman’s methods are most often used in popular software packages to calculate the correlation coefficient between two variables in natural sciences. The (1) difference between them is that the Pearson’s ...
Vremenska distribucija uzroka kašnjenja kao nov pristup otkrivanju baznih uzroka kašnjenja / Temporal distribution of causes of delay as a new approach to discovering the root causes of delay
(27th International project management congress, Vrnjačka Banja, 8-10 June, 2023, 2023)
Građevinski projekti su jedinstveni, dinamični i složeni. Karakteriše ih multidisciplinarno okruženje i veliki broj učesnika koji proizvode značajan obim podataka. Ovo su samo neki od razloga zašto građevinski projekti ne ...
