Sensitivity analysis of variables influencing temperature warping stresses in hydraulic concrete slabs

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 expansi...

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.application/pdfspaspaUniversidad Pedagógica y Tecnológica de Colombiahttps://revistas.uptc.edu.co/index.php/ingenieria/article/view/1340/1335Copyright (c) 2007 Carlos Hernando Higuera Sandovalhttp://purl.org/coar/access_right/c_abf176http://purl.org/coar/access_right/c_abf2Revista Facultad de Ingeniería; Vol. 16 No. 22 (2007); 49-67Revista Facultad de Ingeniería; Vol. 16 Núm. 22 (2007); 49-672357-53280121-1129rigid pavementswarp effortsthermal gradientsdesign of pavimentspavimentos rígidosesfuerzos de alabeogradientes térmicosdiseño de pavimentosSensitivity analysis of variables influencing temperature warping stresses in hydraulic concrete slabsAnálisis de sensibilidad de las variables que influyen en los esfuerzos de alabeo por temperatura en losas de concreto hidráulicoinfo:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_2df8fbb1info:eu-repo/semantics/publishedVersionhttp://purl.org/coar/version/c_970fb48d4fbd8a259http://purl.org/coar/version/c_970fb48d4fbd8a85Higuera Sandoval, Carlos Hernando001/13981oai:repositorio.uptc.edu.co:001/139812025-07-18 11:53:37.601metadata.onlyhttps://repositorio.uptc.edu.coRepositorio Institucional UPTCrepositorio.uptc@uptc.edu.co
