| description | The sensitivity analysis of each of the variables that influence the calculation of the warping stresses produced by the temperature difference of the faces of the hydraulic concrete slab is presented. The variables analyzed were: the modulus of elasticity of the concrete, the coefficient of expansion of the concrete, the temperature difference between the faces of the slab, the thickness of the concrete slab, the Poisson's ratio of the concrete, the modulus of reaction of the slab support, the length of the slab and the width of the concrete slab. Through the sensitivity analysis it is possible to define the degree of importance of the variables and identify the most sensitive ones, or those that affect to a greater or lesser degree the mechanical behavior of concrete slabs due to the effect of temperature changes, in order to have tools that allow pavement design engineers to be certain of the variables that must be modified to ensure that the structural model meets the design requirements and ensures good mechanical behavior of the slab throughout its service life. |

Se presenta el análisis de sensibilidad de cada una de las variables que influyen en el cálculo de los esfuerzos de alabeo producidos por la diferencia de temperatura de las caras de la losa de concreto hidráulico, las variables analizadas fueron: el módulo de elasticidad del concreto, el coeficiente de dilatación del concreto, la diferencia de temperatura entre caras de la losa, el espesor de la losa de concreto, la relación de Poisson del concreto, el módulo de reacción del apoyo de la losa, la longitud de la losa y el ancho de la losa de concreto. Por medio del análisis de sensibilidad es posible definir el grado de importancia de las variables e identificar las más sensibles, o que afectan en mayor o menor grado el comportamiento mecánico de las losas de concreto debido al efecto de los cambios de temperatura, para así tener herramientas que les permitan a los Ingenieros de diseño de pavimentos tener certeza de las variables que deben modificarse para conseguir que el modelo estructural cumpla con los requisitos de diseño y asegure un buen comportamiento mecánico de la losa durante su vida de servicio.
