| description |
This work describes a numerical model of fibre reinforced concrete elastic behaviour implemented using the finite elements method (Hughes, 2000). In structures made of this material, each point is formed by steel fibres embedded into a simple concrete matrix. The reinforced concrete is represented inside a finite element as an orthotropic material having random material direction based on the vanishing diameter fibre model (Dvorak and Bahei-el-Din, 1982) and the mixing theory modified for short length reinforcement (Oller, 2003). Statistical analysis consisted of repeating the problem’s numerical simulation where the direction of fibres was modified by a random function to set up a sampling database from the results and measure their variability. A sensitivity study of finite element size and the number of sampling data was then carried out in terms of total strain energy. Finite element size and sampling data are recommended. The average structural response of a reinforced concrete beam with different quantities of steel fibres where minimum data dispersion was observed is given as an example of applying the above. |

En estructuras hechas de dicho material cada punto está compuesto por fibras cortas de acero embebidas en una matriz de concreto simple. En el interior de un elemento finito el concreto reforzado se representa como un material ortótropo de dirección material aleatoria, basado en el modelo de fibras con diámetro despreciable (Dvorak y Bahei-el-Din, 1982) y la teoría de mezclas modificada para refuerzo de corta longitud (Oller, 2003). El análisis estadístico realizado consiste en: repetir la simulación numérica del problema cambiando la dirección de las fibras mediante una función aleatoria, construir la base de datos de muestreo a partir de los resultados obtenidos y medir la dispersión de estos últimos. A continuación, en este trabajo se estudia la sensibilidad del tamaño de los elementos finitos y del número de datos de muestreo en el cálculo de la energía total de deformación y se establecen algunos valores recomendables. Como ejemplo de aplicación se obtuvo la respuesta estructural promedio de una viga de concreto reforzado con diferentes cuantías de fibras cortas de acero, observando una dispersión mínima de los datos.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/20518Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 31, núm. 1 (2011); 26-38 Ingeniería e Investigación; Vol. 31, núm. 1 (2011); 26-38 2248-8723 0120-5609Lamus, Fabian and Caicedo, Manuel and Linero, Dorian (2011) Numerical modelling of elastic behaviour of concrete reinforced with steel short fibres in plane stress conditions.
