Hydraulic Jumps in Adverse-Slope Stilling Basins for Stepped Spillways
(MDPI AG, 2018)
The performance of flat stilling basins can be inadequate for conditions when the tailwater depth is insufficient for hydraulic jump stabilization. In such cases, adverse-slope stilling basins can be used because they ...
Vibrations measurement using wireless sensor network / Merenje vibracija mrežom bežičnih senzora
(Savez inženjera i tehničara Srbije, Beograd, 2012)
Laboratory prototype of a wireless sensor network (WSN) for vibrations measurements on buildings was developed. The system is comprised of sensor devices (nodes) each having main processor board, accelerometer board, ...
Short-term behaviour of reinforced recycled aggregate concrete beams / Ponašanje armiranobetonskih greda od betona na bazi recikliranog agregata pod kratkotrajnim opterećenjem
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2009)
Recycling of waste concrete is one of the sustainable solutions for growing waste disposal crisis and depletion of natural aggregate sources. As a result of that process, recycled aggregate (RCA) is produced and it is used ...
Influence of acid treatment and carbonation on the properties of recycled concrete aggregate
(Savez hemijskih inženjera, Beograd, 2018)
Recycled concrete aggregate (RCA), obtained by crushing of original (old) concrete, consists of natural aggregate grains and a cement mortar matrix. The presence of old adhered cement mortar, which has higher porosity than ...
Adverse-slope stilling basins: machine learning approach to estimation of hydraulic jump features
(SDHI/SDH, 2018)
Stilling basins are the most commonly used energy dissipating structure for large dams, due to their high operating reliability under a wide range of inflow conditions. However, unsatisfactory tailwater conditions, primarily ...
Determination of pH in Powdered Concrete Samples or in Suspension
(Basel : MDPI, 2019)
Concrete is a material that is widely used by mankind. Although different deterioration mechanisms can lead to degradation of the concrete itself, reinforcement corrosion is the biggest durability issue for reinforced ...
Recycled Aggregate Mortar Made with the Recycled Concrete Aggregate and Fly Ash
(Union of Mechanical and Electrotechnical Engineers and Technicians of Serbia (SMEITS) Society for Renewable Electrical Power Sources, 2022)
With the aim of sustainable development of the construction industry, a large number of theoretical and practical research is currently being carried out on the possibilities of using various recycled materials in cement ...
Rekonstrukcija krovne konstrukcije crkve Karmelskog manastira u Somboru
(Društvo građevinskih konstruktera Srbije, Beograd, 2016)
Flexural buckling of hot-finished and cold-formed elliptical hollow section columns: Numerical comparative analysis / Fleksiono izvijanje naknadno termički obrađenih i hladnooblikovanih stubova elipsastog poprečnog preseka: Numerička uporedna analiza
(Beograd : Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, 2019)
Even though structural elements of the elliptical hollow section (EHS) have been introduced to the construction market in the past years, the rules for their design were only partially introduced into the suitable codified ...
Koncept proračuna sekundarnih seizimčkih elemenata prema Evrokodu 8
(Društvo građevinskih konstruktera Srbije, Beograd, 2016)
U radu je analiziran koncept proračuna armiranobetonske konstrukcije sa sekundarnim seizmičkim elementima prema zahtevima Evrokoda 8. Iako se doprinos krutosti ovih elemenata zanemaruje prilikom seizmičkog odgovora ...
