Methods of damage detection of structures based on changes of dynamic characteristics / Metode detekcije oštećenja konstrukcija na osnovu promene dinamičkih karakteristika
(Savez građevinskih inženjera Srbije, Beograd, 2015)
The paper presents overview of damage detection of structures using non destructive test methods and corresponding optimization procedures for detection, localization and severity of damage. Change of a stiffness, as a ...
Development of consistent design storms / Konsistentno određivanje računskih kiša
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
Design storms are the basic input for hydrologic assessment and design of the flood control structures. Small and medium sized catchments with shorter concentration times require design storms of shorter, sub-daily, duration, ...
Analysis of the embodied energy and the CO2 emission in construction process of a bridge structure from the aspect of sustainability / Analiza vezane energije i emisije CO2 za izvođenje mostovske konstrukcije sa stanovišta održivosti
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2015)
This paper presents a comparative analysis of embodied energy and CO2 emission, in the construction process of three bridge structures. Analyzed structures are prestressed concrete bridges with different structural systems ...
Analysis of hydrodynamic pressures in the stilling basin of an earth dam
(Serbian Water Pollution Control Society, Belgrade, 2015)
The stilling basin is one of the most frequently used energy dissipation structures due to highly-efficient energy dissipation of the main stream through the secondary turbulent flow in the hydraulic jump roller formed ...
Numerical modeling of supercritical flow in closed conduit bend / Numeričko modeliranje burnog tečenja u krivini zatvorenog provodnika
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
Numerical modeling of supercritical flow in closed conduit bend is a continuation of the scale model experiments. The main goal of application of numerical model is to extend the range of investigation and to simulate ...
Application of layered finite elements in the numerical analysis of laminated composite and sandwich structures with delaminations / Primena slojevitih konačnih elemenata u numeričkoj analizi laminatnih kompozitnih i sendvič-ploča i ljuski s delaminacijama
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2015)
Laminar composites are modern engineering materials widely used in the mechanical and civil engineering. In the paper, some recent advances in a numerical analysis of laminated composite and sandwich plates and shells of ...
Bending behaviour of glulam beams reinforced with carbon FRP plates
(Taylor and Francis Ltd., 2015)
The idea of reinforcing glued laminated timber (glulam) beams came in response to the need to improve the mechanical properties, as well as to ensure higher reliability of this type of structural elements. This paper ...
Specific features of stainless steel compression elements
(Union of Croatian Civil Engineers and Technicians, 2015)
Stainless steel has a number of features that define different behaviour of structural elements made of this material, as related to equivalent carbon steel elements. These properties, especially prominent in case of ...
Primena modela razmene količine kretanja u analizi uticaja geometrije i hidrauličkih otpora na osnovne odlike tečenja u koritu za veliku vodu / Study of the influence of channel geometry and hydraulic resistance on flow characteristics in compound channels with the exchange discharge method
(Srpsko društvo za odvodnjavanje i navodnjavanje, 2015)
U radu je sproveden niz numeričkih ogleda sa ciljem da se utvrdi kako geometrija korita za veliku vodu (KVV) i rapavost plavnih površina utiču na razmenu količine kretanja (RKK) između glavnog korita i plavnih površina i ...
Competitive sorption of silver, zinc and copper ions on different types of sorbent / Komparativna sorpcija jona teških metala na različitim tipovima sorbenata
(Jugoslovensko društvo za odvodnjavanje i navodnjavanje, Beograd, 2015)
In this master thesis the sorption of heavy metals on activated carbon and zeolite was analyzed. The chosen heavy metals (Ag+, Cu2+, Zn2+) have been analyzed separately and as a mixture in order to check their sorption ...
