Comparación de modelación por Inteligencia Artificial y Regresión Multivariable del comportamiento a flexión del UHPFRC

Abstract: El estudio presentado tiene como objetivo modelar el comportamiento a flexión de los concretos de ultra alto desempeño reforzados con fibras (UHPFRC), incluyendo límite de proporcionalidad (LOP), módulo de rotura (MOR) y sus deflexiones asociadas δLOP y δMOR, utilizando análisis de regresión multivariable y algoritmos de inteligencia artificial (AI). Se construyeron cuatro modelos redes neuronales artificiales (ANN), uno para cada respuesta, con una capa de entrada y una capa oculta, y cuatro modelos de regres… Show more

“…The latter is consistent with a large number of researches conducted during the last two decades [76,84,115]. Specifically, the fiber reinforcement index is a key factor in the fiber bridging capacity, which highly affects both the post-cracking strength and its related strain [9], which are decisive for the computation of the g-value [38,42,116].…”

“…The literature review shows that substituting some of the Portland cement with GP diminishes the resistance to bending in plain UHPC formulations [15,62]. However, while it is notable that the flexural strength lowers with increasing substitution of GP in the case of plain UHPC, it is important to recognize that in fiber-reinforced UHPC, the primary determinant of performance is the fiber reinforcement system [126][127][128]. Neira-Medina et al [15] researched to analyze the impact of different fiber-reinforced systems on the flex- The study also established that concrete of superior quality typically exhibits an ultrasonic pulse velocity exceeding 4575 m/s.…”
