Long-term change in hydroclimatic regimes in catchments across Serbia
(Faculty of Geography, Lomonosov Moscow State University, 2023)
This study presents trend analyses in several catchments across Serbia. The trend analyses are preformed over series of precipitation, temperature and streamflows. These variables are represented by different indicators, ...
Free vibration analysis of stiffened and cracked laminated composite plate assemblies using shear-deformable dynamic stiffness elements
(Elsevier Ltd, 2017)
In the paper, the dynamic stiffness method based on the HSDT and FSDT plate theories is applied to study free vibration characteristics of composite stiffened and cracked plate assemblies. The dynamic stiffness matrices ...
Efficient Adaptive Section Discretization Schemes
(Conference: Third European Conference on Earthquake Engineering and Seismology, 2022)
The paper summarises a family of adaptive fiber section discretization schemesfor nonlinear frame elements. The proposed schemes use cubature integration rules forintegration within the linear-elastic part of a section and ...
Shrinkage of recycled aggregate concrete: experimental database and application of fib Model Code 2010
(Springer Netherlands, 2018)
This paper describes a meta-analysis of previously published studies on the shrinkage strain of recycled aggregate concrete (RAC). The study aims at providing an analytic expression for the shrinkage strain of RAC to be ...
Utilization of recycled waste concrete aggregates in structural concrete
(Nova Science Publishers, Inc., 2011)
One of the biggest environmental problems in the majority of the world today is a generation of huge amounts of waste. Amongst various types of waste, construction and demolition (C&D) waste makes almost the half of the ...
Nonlinear finite element anal ysis of punching strength of lift slabs at edge columns
(Publisbing Company of Budapest University of Tecbnology and Economics, 2005)
The experimental investigation of punching shear strength of post-tensioned lift slab-edge column connection was simulated using the DIANA Finite Element System. One of the tested specimens was modeled by solid elements ...
Flow measurement methodology for low head and short intake bulb turbines - Iron Gate 2 case
(International group for hydraulic efficiency measurement (IGHEM), 2022)
Flow measurement of low head turbines, with short intakes like bulb turbines is challenging since there is no “regular” cross-section with fully developed velocity profile. In most situations the flow data during field ...
Uncertainty assessment of flow measurements at Iron Gate 2
(International group for hydraulic efficiency measurement (IGHEM), 2022)
To allow for the reliable hydraulic efficiency estimation of the tubular turbines before and after their revitalization at the Hydro Power Plant (HPP) Iron Gate 2, a novel flow measurement system was designed and tested ...
Sanacija oštećenja lepljenih lameliranih drvenih greda sa redukovanom visinom preseka kod oslonaca pomoću GFRP šipki
(Savez građevinskih inženjera Srbije, 2020)
U radu je predstavljeno eksperimentalno ispitivanje mogućnosti sanacije oštećenih lepljenih lamliranih drvenih greda sa redukovanom visinom preseka kod oslonaca pomoću šipki na bazi polimera ojačanih staklenim vlaknima ...
Influence of Fly Ash as Cement Substitution on Accelerated and Natural Carbonation of Concrete
(Springer, Cham, 2023)
The use of fly ash (FA) for the production of new concrete seems to be a promising solution for “greening” of construction industry. However, re-placement of cement with supplementary cementitious materials such as fly ash ...
