Identification of steel bars immersed in reinforced concrete based on experimental results of eddy current testing and artificial neural network analysis
This paper presents an experimental research on the use of eddy current testing (ECT) and artificial neural networks (ANNs) in order to identify the gauge and position of steel bars immersed in concrete structures. The ...
A finite element approach for predicting the ultimate rotation capacity of RC beams
This paper presents a numerical approach to model the complex failure mechanisms that define the ultimate rotational capacity of reinforced concrete beams. The behavior in tension and compression is described by a constitutive ...
Structural analyzes of the use of residues of tires in reinforced concrete
The search for an adequate destination to the tires without use is a problem for many countries. The use of tire rubber in concrete through the partial substitution of the small aggregate has for objective the withdrawal ...
Electrical resistivity measurement of unsaturated concrete samples
(ICE Publishing, 2014-04)
Electrical conduction in concrete primarily occurs via the liquid in pores. Since concrete resistivity is sensitive to moisture content, resistivity can be used to infer other moisture-dependent concrete properties. However, ...
Steel bars identification in reinforced concrete structures by using ANN and magnetic fields
This work proposes a methodology for non destructive testing (NDT) of reinforced concrete structures, using superficial magnetic fields and artificial neural networks, in order to identify the size and position of steel ...
HIGH STRENGTH CONCRETE: THE REINFORCED CONCRETE OF THE CENTURY 21(ST)
(Univ Politecnica Catalunya, 2007-01-01)
This work is about the 21st century reinforced concrete analysis under the point of view of its constituent materials. First of all it is described the theoretical approach of the bending elements calculated based on the ...
