[EN] There is a need to establish a complete process to characterize Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC) in both strain-hardening and strain-softening tensile behavior. This process should be simple ...
[EN] This paper presents a study on the flexural behavior of Ultra-High-Performance Fiber-Reinforced Concrete (UHPFRC) beams, which included conventional reinforcing bars. The study focuses on critical design aspects, such ...

[EN] The push-off test has been used to study the mechanisms of shear transfer of reinforced concrete elements. It is assumed that shear stress is constant along the shear plane. The objective of this paper is to understand ...
[EN] Self-healing is the capability of a material to repair its damage autonomously. Ultra-High-Performance Fiber Reinforced Concrete (UHPFRC) has potentially higher self-healing properties than conventional concrete because ...

This paper aims at studying the shear contribution of steel fibres in concrete. Ten reinforced concrete (RC) and steel-fibre reinforced concrete (SFRC) initially uncracked push-off specimens were tested. Average normal and ...
[EN] Reinforced concrete elements frequently suffer small cracks that are not relevant from the mechanical point of view, but they can be an entrance point for aggressive agents, such as oxygen, which could initiate the ...
[EN] Although recent years have been marked by a substantial research effort on the progressive collapse of steel as well as cast-in-place and precast concrete structures, the fact is that almost all studies are focused ...

[ES] El colapso progresivo puede definirse como el proceso por el cual un daño local inicial pone en marcha una cadena de fallos, que a veces puede conducir a un colapso desproporcionado o total. Se trata de un fenómeno ...
[EN] Nowadays, the characterization of Ultra-High Performance Fiber-Reinforced Concrete (UHPFRC) tensile behavior still remains a challenge for researchers. For this purpose, a simplified closed-form non-linear hinge model ...
