La definición de relaciones fundamentales como la de esfuerzo-deformación, que permite diseñar estructuras de manera eficiente, adecuada y segura, deviene de extensas campañas experimentales. El uso de estos pórticos posibilita la investigación multidisciplinaria en las materias relacionadas con el estudio de materiales y también permite el estudio detallado de elementos estructurales fabricados con diferentes materiales, elementos de reuso que puedan provenir de procesos industriales como fibras naturales o residuos de vidrio. Los resultados obtenidos a partir de ensayos principalmente sobre vigas, permiten establecer la línea de investigación en materiales y elementos estructurales a partir del estudio de las relaciones esfuerzo-deformación para posibilitar la estimación de propiedades de elasticidad y de resistencia en materiales como acero, hormigón armado, muros, entre otros. El presente trabajo tiene el propósito de mostrar las facultades del empleo de pórticos de ensayos para disminuir la brecha entre la formación teórica y la aplicación práctica a nivel académico e investigativo dentro la ingeniería estructural y de materiales, a través de una revisión de la evolución y la utilidad de este tipo de elementos en la enseñanza. Con este fin, se desarrolla una revisión bibliográfica de trabajos desarrollados principalmente a nivel Latinoamericano en laboratorios que cuentan con pórticos de ensayos, se describe la evolución de estos elementos, las características principales de pórticos en el medio, las normativas asociadas al desarrollo de pruebas en estos equipos y finalmente se realiza un breve análisis de resultados experimentales y su relevancia en la academia y la investigación.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The gantries for laboratory experimentation constitutes a transcendental tool for the characterization of the mechanical behavior of structural elements made of various materials. The definition of fundamental relationships, such as stress-strain, which allows to design structures efficiently, appropriately, and safely, arises from extensive experimental campaigns. Moreover, the use of gantries for testing the properties of different materials allows the implementation of research at different engineering courses related with the study of materials; also, it allows to study the behavior of different materials and innovative materials for structural use, such as those resulting from industrial processes like rice natural fiber or glass powder. The preliminary experimentation and the results obtained were conducted on wood elements, and they are part of a research line looking for a better understanding of elasticity properties in materials such as steel, reinforced concrete, masonry, among other. The present work aims to demonstrate the capabilities of using testing porticos to bridge the gap between theoretical knowledge and practical application at the academic and research levels within structural engineering. This is achieved through a review of the evolution and usefulness of these elements in education. With this purpose, a bibliographic review of works developed mainly at the Latin American level in laboratories equipped with gantries is conducted. The evolution of these elements is described, along with the main characteristics of different gantries. Standard practices associated with conducting tests on these devices are also presented, and finally, a brief analysis of experimental results and their relevance in academia and research is performed.]]></p></abstract>
