Direct procedure to characterize the tensile constitutive behavior of strain-softening and strain-hardening UHPFRC

Mezquida-Alcaraz, Eduardo J.; Navarro-Gregori, Juan; Serna Ros, Pedro (Elsevier, 2021-01)

[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 ...
Effects of tension stiffening and shrinkage on the flexural behavior of reinforced UHPFRC beams

Mezquida-Alcaraz, Eduardo J.; Navarro-Gregori, Juan; Martí Vargas, José Rocío; Serna Ros, Pedro (Elsevier, 2021-12)

[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 ...
Estudio experimental y modelización numérica del comportamiento frente a tensiones tangenciales de elementos de hormigón armado y hormigón armado y reforzado con fibras de acero

Mezquida Alcaraz, Eduardo José (Universitat Politècnica de València, 2016-07-06)

[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 ...
Evaluation of the Self-healing Capability of Ultra-High-Performance Fiber-Reinforced Concrete with Nano-Particles and Crystalline Admixtures by Means of Permeability

Doostkami, Hesam; Roig-Flores, Marta; Negrini, Alberto; Mezquida-Alcaraz, Eduardo J.; Serna Ros, Pedro (Springer, 2020-09-22)

[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 ...
Experimental study on the steel-fibre contribution to concrete shearbehaviour

Navarro-Gregori, Juan; Eduardo José Mezquida Alcaraz; Serna Ros, Pedro; Echegaray-Oviedo, Javier Andres (Elsevier, 2016-06)

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 ...
Influence of cracking on oxygen transport in UHPFRC using stainless steel sensors

Martínez-Ibernón, Ana; Roig-Flores, Marta; Lliso-Ferrando, Josep Ramon; Mezquida-Alcaraz, Eduardo J.; Valcuende Payá, Manuel Octavio; Serna Ros, Pedro (MDPI AG, 2020-01)

[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 ...
Large-Scale Tests on RC Purpose-Built Buildings for Improving Robustness

Buitrago, Manuel; Makoond, Nirvan Chandra; Mezquida-Alcaraz, Eduardo J.; Adam, Jose M. (Springer Cham, 2023-06-07)

[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 ...
Modelo numérico para la caracterización del comportamiento de las propiedades a tracción del UHPFRC

Caceres Vergara, Vladimir (Universitat Politècnica de València, 2023-04-06)

[ES] La tecnología del hormigón ha avanzado notablemente en las últimas décadas, siendo el Hormigón de muy Alto Rendimiento (Ultra-High-Performance Fiber-Reinforced Concrete, UHPFRC) uno de los tipos de hormigón de mayor ...
Numerical Modelling of UHPFRC: from the Material to the Structural Element

Mezquida Alcaraz, Eduardo José (Universitat Politècnica de València, 2021-05-30)

[ES] El principal objetivo de la presente tesis es el desarrollo de una completa metodología para el modelado numérico del UHPFRC desde el material hasta el elemento estructural. Se pretende contribuir al avance del ...
Preliminary study on the fresh and mechanical properties of UHPC made with recycled UHPC aggregates

Roig-Flores, Marta; Borg, Ruben Paul; Ruiz-Muñoz, Cecilia; Mezquida-Alcaraz, Eduardo J.; Gimenez-Carbo, Ester; Lozano Násner, Albany Milena; Serna Ros, Pedro (Taylor & Francis, 2022-11-18)

[EN] The recycling of construction and demolition waste material reduces disposal of material and also the consumption of resources, therefore promoting sustainability in construction. Ultra-high performance concrete (UHPC) ...
Robustez de estructuras prefabricadas de hormigón: simulación computacional mediante applied element method

Buitrago, Manuel; Makoond, Nirvan Chandra; Mezquida-Alcaraz, Eduardo J.; Adam, Jose M. (International Center for Numerical Methods in Engineering (CIMNE), 2022-09-14)

[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 ...
Validation of a non-linear hinge model for tensile behavior of UHPFRC using a Finite Element Model

Mezquida-Alcaraz, Eduardo J.; Navarro-Gregori, Juan; Lopez Martinez, Juan Angel; Serna Ros, Pedro (Techno-Press, 2019)

[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 ...
