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 ...
Dynamic stiffness – based free vibration study of open circular cylindrical shells
(Elsevier, 2020)
In this paper, the dynamic stiffness method has been applied in the free vibration analysis of open circular cylindrical shells based on Flügge thin shell theory. The dynamic stiffness matrix for a completely free open ...
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 ...
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 ...
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 ...
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 ...
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 ...
The role of service life in Life Cycle Assessment of concrete structures
(Elsevier Ltd, 2020)
In comparative Life Cycle Assessment (LCA) of concrete structures it is of crucial importance to provide the functional equivalence of compared alternatives. Most commonly, the comparison is performed between the structures ...
