On the extension of the Erdös-Mordell type inequalities
(Mathematical Inequalities & Applications, 2014)
We discuss the extension of inequality R_A >= c/a * r_b + b/a * r_c to the plane of triangle ABC. Based on the obtained extension, in regard to all three vertices of the triangle, we get the extension of Erdos-Mordell ...
Deflection control for reinforced recycled aggregate concrete beams: Experimental database and extension of the fib Model Code 2010 model
(Structural Concrete, 2019)
Recycled aggregate concrete (RAC) has emerged as a viable solution for
solving some of the environmental problems of concrete production.
However, design guidelines for deflection control of reinforced RAC
members have ...
Long-term behaviour of reinforced beams made with natural or recycled aggregate concrete and high-volume fly ash concrete
(Elsevier, 2018)
Six simply supported reinforced concrete beams were tested under sustained loads for 450 days. The beams were made from natural aggregate concrete (NAC), recycled aggregate concrete (RAC) and high-volume fly ash concrete ...
Effect of rib-to-beam angle on the shear resistance of headed studs in composite slab
(Elsevier, 2024)
Headed stud shear connectors are commonly implemented in steel-concrete composite floors for connecting the concrete slab to the steel beam and providing composite action between those two elements. The orientation of ...
Shear behaviour of recycled aggregate concrete beams with and without shear reinforcement
(Engineering Structures, 2017)
An experimental study of the shear behaviour of recycled aggregate concrete (RAC) beams with and without shear reinforcement is presented. Nine full-scale simply supported beams were loaded in four-point bending tests until ...
Flexural behaviour and ultimate bending capacity of high-volume fly ash reinforced concrete beams
(Engineering Structures, 2023)
Large number of studies analyzed physical and mechanical properties of high-volume fly ash concrete, but only a few discussed its structural behavior. Material properties are an important input parameter for structural ...
A database on flexural and shear strength of reinforced recycled aggregate concrete beams and comparison to Eurocode 2 predictions
(Construction and Building Materials, 2016)
A comprehensive database of recycled aggregate concrete and companion natural aggregate concrete beams’ flexural and shear strength was compiled from 217 experimental results. Strict criteria were applied to determine the ...
Application of geophysical and multispectral imagery data for predictive mapping of a complex geo‑tectonic unit: a case study of the East Vardar Ophiolite Zone, North‑Macedonia
(Springer-Verlag GmbH Germany, 2024)
The Random Forest (RF) and K nearest neighbors (KNN) machine learning (ML) algorithms were evaluated for their ability to predict ophiolite occurrences, in the East Vardar Zone (EVZ) of central North Macedonia. A predictive ...
Environmental assessment of green concretes for structural use
(Journal of Cleaner Production, 2017)
This paper presents a comparative environmental assessment of several different green concrete mixes
for structural use. Four green concrete mixes were compared with a conventional concrete mix: recycled
aggregate concrete ...
Prediction model for calculation of the limestone powder concrete carbonation depth
(Elsevier Ltd, 2024)
The efficient way to mitigate the impact of the concrete industry on climate change is to reduce the clinker content in the concrete mix. Beside incorporating supplementary cementitious materials (SCMs), it is possible to ...
