Resumen
La presente investigación se desarrolló a propuesta del departamento de Ingeniería Civil de la Facultad de Construcciones, específicamente por la disciplina de análisis y diseño estructural, por la necesidad de reunir en un mismo documento la mayor cantidad de información sobre el análisis y diseño de las uniones metálicas. Además se confecciona un0 libro electrónico en Mathcad que facilite el trabajo de los estudiantes a la hora de diseñar las uniones más comunes, tanto atornillada como soldada.
Se presenta una selección de uniones metálicas entre diferentes elementos estructurales, entre ellas las uniones viga-viga, uniones viga-columna y uniones columna ménsula. Para el estudio de las metodologías de diseño y/o revisión de dichas uniones se utilizó el método elástico, debido a que el análisis por resistencia última a pesar de dar resultados más exactos, requiere de un trabajo más complejo, siendo necesaria la utilización de una gran cantidad de tablas. Las metodologías se presentan en forma de diagramas de flujo lo cual facilita el entendimiento de las mismas y la confección de las hojas de cálculo.
También se realiza una comparación entre los resultados obtenidos de diferentes diseños manualmente y mediante la utilización de las hojas de cálculo. A partir de lo cual se presentan conclusiones y recomendaciones para enfrentar el diseño de uniones metálicas y facilitar el trabajo de las mismas.
The current research was developed by taking into account a proposal from the Department of Civil Engineering, School of Constructions, specifically by the discipline of structural analysis and design, due to the need of bringing together in one document as much information about the analysis and design of metal joints as possible. In addition, an e-book in Mathcad is elaborated in order to facilitate the students ‘work when designing the most common joints, both bolted and welded. A selection of metal joints is presented between different structural elements, including the beam-beam bonds, beam-column joints and column bracket. Elastic method was used to help the study of design methodologies and / or review of such unions, because the analysis by last strength, despite giving more accurate results, requires a more complex job, being necessary many tables. The methodologies are presented in the form of flowcharts which facilitates the understanding of them and the production of spreadsheets. A comparison between the results of different designs obtained manually and using spreadsheets is also performed, from which findings and recommendations to address the design of metal joints and facilitate the work with them are presented.
