Resumen
El análisis y la ingeniería de los puentes ha sido revolucionado con el desarrollo de los métodos numéricos aplicados en softwares profesionales. En el presente trabajo se realiza la implementación de Hojas de Cálculo elaboradas en MathCad con el método correspondiente para análisis de puentes de losa y puentes de vigas y losas para su uso en la docencia. Se aportan para comparar los resultados con los obtenidos por softwares profesionales que practiquen la modelación por elementos finitos como son el SAP 2000 y el STAAD Pro para llegar a concluir cual es el programa para la modelación de superestructuras de puentes que arroje resultados satisfactorios para ser aplicado en la docencia y en al ámbito profesional.
Se realiza un estudio detallado relacionado con cada método de análisis de puente que se va a utilizar (método de Westergaard, método de la AASHTO, y método de Guyon-Massonnet-Bares), así como para los programas correspondientes y su forma de trabajar.
The analysis and engineering of the bridges has been revolutionized with the development of numerical methods applied in professional software. In the present work the implementation of Worksheets elaborated in MathCad with the corresponding method is analyzed for slab bridges and bridges of beams and slabs for their use in teaching. They contribute to compare the results with those obtained by professional software that practice finite element modeling such as SAP 2000 and STAAD Pro to arrive to conclude what is the program for the modeling of superstructures of bridges that yield satisfactory results to be applied in teaching and in the professional field. A detailed study is carried out related to each method of bridge analysis to be used (Westergaard method, AASHTO method, and Guyon-Massonnet-Bars method), as well as for the corresponding programs and their way of working.
