[EN] The shear strength of elements reinforced by fibres is predicted by Codees using formulations generally developed from a limited set of test results.
Characterisation of the tensile behaviour of UHPFRC remains a challenge for researchers, and an
agreement on the standard test set-up and advisability of notch is yet to be reached. Bending tests are
easier to conduct ...

This paper presents a model for the analysis of reinforced concrete beams under monotonic loading conditions, including axial, bending, and shear forces, in order to effectively capture the mechanisms of shear transfer. ...
[EN] The following TFM includes a study on the behavior of the current vertical docks for the docking of mega container ships; focusing on the dimensioning of the cantile beams needed to withstand the future and much greater ...
[ES] El Ultra High Performance Concrete (UHPC) es un material de construcción innovador que combina las tres propiedades punteras de los hormigones como son la alta resistencia, la autocompactabilidad y el empleo de fibras ...
Structural engineers usually limit the use of HSC columns to seismic active zones because of their brittle behavior in comparison with NSC, even though it presents advantages both in terms of mechanics and durability. A ...
[EN] Shear behaviour in reinforced concrete (RC) elements can improve with an adequate amount of fibres. Research has recently determined how fibres affect shear strength, but has barely focused on macro synthetic ...
[EN] The determination of the tensile properties of such a deflection hardening response material as UHPFRC is a serious challenge for both researchers and designers. This process involves many factors, such as specimen ...
An experimental investigation to determine the transfer length of a seven-wire prestressing
strand in different concretes is presented in this paper. A testing technique based on the analysis of bond
behaviour by means ...
Una gran cantidad de edificios se construyen utilizando muros de corte de hormigón armado, para brindar mayor rigidez y resistencia a esfuerzos horizontales producidos por las acciones del sismo y del viento. La gran mayoría ...
[ES] El presente trabajo estudia mediante técnicas de fotogrametría el comportamiento de fisuras

The inclusion of ductility requirements is necessary to guarantee the safety design of any concrete structure
subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may be
developed ...
This paper presents an experimental research work to determine both the transmission and the anchorage
lengths of seven-wire prestressing steel strands in different concrete mixes. A testing technique
based on a bond ...
Combining the most recent technologies in concrete, Ultra-High-Performance Fibre-Reinforced Concrete (UHPFRC) arises as a promising material for the near future. UHPFRC have shown how flexible concrete can be to adapt to ...
