Abstract
A nivel nacional, en los principales proyectos en los que se utilizan los ensayos propuestos en la recomendación EFNARC de 1996, a saber, ensayos de panel para determinar la capacidad de absorción de energía y de vigas para determinar las resistencias residuales y tenacidad del hormigón reforzado con fibras. No obstante, no existen en la literatura resultados que permitan establecer una correlación o equivalencia entra ambos ensayos, lo que obliga a tomar un gran número de muestras en las obras, las que en general son de grandes dimensiones y peso, dificultando la manipulación especialmente al interior de túneles en construcción.El objetivo de la presente memoria es establecer una equivalencia en la capacidad de absorción de energía de los shotcrete reforzado con fibras, determinada mediante ensayos de panel EFNARC, y la tenacidad de los hormigones reforzados con fibras, obtenida mediante viga EFNARC.Para lograr el objetivo propuesto se elaborarán y ensayarán paneles y vigas de hormigones reforzados con fibras de acero y sintéticas, de acuerdo a las disposiciones de la recomendación EFNARC 1996. Con los resultados alcanzados, se propondrán correlaciones que permitan simplificar las faenas de control en las obras.
Up to a national level, the main projects in which the trials proposed by the 1996 EFNARC recommendation, known as, panel trials to determine the power of absorption of energy and the beams to determine the residual resistance and tenacity of the reinforced concrete with fiber. Nevertheless, there is not any information yet that can lead to establish a correlation or equivalence between both trials, which requires taking a big number of samples on site, which are generally heavy in dimension and weight, which is difficult to manipulate especially inside tunnels in the middle of construction.The aim of the present work is to establish an equivalence in the power of absorption of energy from shotcrete with fiber, determined through EFNARC panel trials, and the tenacity of the reinforced concrete with fiber obtained through EFNARC beams.To achieve the goal set, panels and reinforced concrete beams will be made and tested with steel and synthetic fiber, according to the 1996 EFNARC recommendations and regulations. With the results obtained, correlations that allow to simplify the security controls at the construction site will be proposed.
