Estudio del comportamiento de vigas de hormigón pretensado reforzado con fibras de acero (HPRF)

Abstract

La adición de fibras al hormigón mejora el comportamiento a cortante de un elemento estructural. Sin embargo, hay una mayor cantidad de trabajos científicos referidos a la evaluación de los efectos de las fibras en elementos estructurales de hormigón armado que en elementos pretensados. En este trabajo se estudia numéricamente el comportamiento de vigas de HPRF ensayadas a corte por otros investigadores, a fin de evaluar la contribución de las fibras. El objetivo es contribuir al diseño eficiente de este tipo de vigas. Para ello, se modela un ensayo de corte y se calibran los parámetros del modelo constitutivo, comparando los resultados numéricos con los experimentales. Luego, se utiliza el modelo numérico para reproducir el comportamiento de una viga de HPRF ensayada experimentalmente.

The addition of fibers to concrete improves the shear behavior of structural elements. However, there is a greater amount of scientific works related to the evaluation of fibers’ effect on reinforced concrete structural elements than in prestressed elements. The behavior of SFRPC beams shear-tested by other researchers is numerically studied in this paper, in order to evaluate the contribution of the fibers. The objective is contributing to the efficient design of this type of beams. For that purpose, a shear test is modeled and the constitutive model parameters are calibrated comparing the numerical and experimental results. Then, the numerical model is used to reproduce the behavior of an experimentally tested SFRPC beam.
