Obezbeđenje lokalne duktilnosti AB elemenata po Evrokodu 8 - koeficijent utezanja
(Društvo građevinskih konstruktera Srbije, Beograd, 2018)
U ovom radu posebna pažnja je usmerena na efekte utezanja preseka, tj. na način na koji transverzalna armatura utiče na ojačavanje, kako materijala, tako i utegnute zone elementa. Da bi se pojasnilo praktično značenje ...
Reuse of Waste Sulfur as a Binding Agent in Concrete
(Association for Promotion of Holistic Approach to Environment, Buzetska 25 44000 Sisak, Republic of Croatia, 2018)
The quantities of component materials used for production of concrete are high on the global scale, therefore alternative materials are experimented on, in order to replace the natural ones. The possibility of using ground ...
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 ...
Life Cycle Cost Management of Concrete Structures
(IABSE Conference 2018 –Engineering the Past, to Meet the Needs of the Future June 25-27 2018, Copenhagen, Denmark, 2018)
Tools, guidelines and standards for assessment of Life Cycle Cost (LCC) of built environment e.g. buildings, infrastructure assets etc. have gained impact over the past years. Owner and operator application of tools, ...
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 ...
Recent research on ductility of perforated shear connectors
(Društvo građevinskih konstruktera Srbije, Beograd, 2018)
Significant implementation of Perfobond shear connectors in construction of composite steel-concrete structures resluted in development of entirely new type of shear connectors, denoted as perforated shear connectors. ...
Crack initiation of selected geopolymer mortars with hemp fibers
(Ecf22 - Loading and Environmental Effects On Structural Integrity, 2018)
The aim of this paper is to quantify particularly fracture properties of selected types of mortars prepared with an alkali activated binder and hemp fibers. The main attention is focused on evaluation of three-point bending ...
Resistance of cold-formed built-up stainless steel columns - Part II: Numerical simulation
(Elsevier Ltd, 2018)
In parallel with an experimental investigation of the flexural buckling behaviour of built-up stainless steel columns presented in the accompanying paper (Dobric et al., submitted for publication), a detailed Finite Element ...
FE validation of the equivalent diameter calculation model for grouped headed studs
(Techno Press, 2018)
Existing design codes for steel-concrete composite structures give only general information about the shear connection provided by headed studs in group arrangement. Grouting of the openings in prefabricated concrete slabs, ...
