This research aims to determine the actual deflection of a concrete joist and to correlate the result with the theoretical deflection. This is based on the theories of elasticity as the double integration method, considering the homogeneous, isotropic and linearly elastic material from an ideal theoretical model. The construction of a concrete joist does not make a 100% homogeneous, isotropic and linearly elastic element, since its manufacture depends on many conditions such as the choice of aggregates, water, the manufacture of cement, tests carried out for the elaboration of the mix design, the operator who is going to perform the mix and the construction of the joist. The variation of the real deflection with respect to the theoretical one has been investigated. For this, 30 simple concrete joists and 30 reinforced concrete joists were manufactured. The dimensions of these joists were 15cm x15cmx53.5cm (b x h x L). The reinforcement of the last 30 joists was 4 Փ 1/4 "as longitudinal reinforcement and Փ 1/4" @ 0.10 m of transverse reinforcement. The joists were tested for flexion by measuring the maximum deflection and compared with the theoretical one, calculated by the double integration method, having much greater experimental results than those calculated with the theory of the double integration method, not being within the ranges expected in literature
La presente investigación tiene como objetivo determinar la deflexión real de una vigueta de concreto y correlacionar el resultado con la deflexión teórica. Esta se fundamenta en las teorías de la elasticidad como el método de la doble integración, considerando el material homogéneo, isótropo y linealmente elástico a partir de un modelo teórico ideal. La construcción de una vigueta con concreto no conforma un elemento 100% homogéneo, isótropo y linealmente elástico, ya que su fabricación depende de muchas condiciones como la elección de los agregados, el agua, la fabricación del cemento, los ensayos realizados para la elaboración del diseño de mezclas, el operario que va a realizar la mezcla y la construcción de la vigueta. Se ha investigado la variación de la deflexión real respecto de la teórica. Para ello, se fabricaron 30 viguetas de concreto simple y 30 viguetas de concreto armado. Las dimensiones de estas viguetas fueron de 15cm x15cmx53.5cm (b x h x L) la armadura de las últimas 30 viguetas fue de 4Փ1/4” como refuerzo longitudinal y Փ1/4” @0.10 m de refuerzo transversal. Las viguetas se ensayaron a flexión midiendo la deflexión máxima y se comparó con la teórica, calculada por el método de la doble integración, teniendo resultados experimentales mucho mayores que las calculadas con la teoría del método de la doble integración, no estando dentro de los rangos esperados en la literatura.
