Abstract
El presente trabajo se enmarca en un proyecto de investigación llevado adelante en el CECOVI dentro de la Facultad Regional Santa Fe, de la Universidad Tecnológica Nacional. La utilización de vigas reticuladas diseñadas con perfiles conformados en frío de sección C se ha popularizado en el país en construcciones de galpones de pequeña envergadura. El presente trabajo pretende analizar en detalle la conexión entre barras, en los casos en que las diagonales se sueldan al labio rigidizador del cordón conformando una solución compleja de evaluar por medios tradicionales de análisis. A su vez, la solución no utiliza medios auxiliares de conexión como chapas de nudo, generando excentricidades en el encuentro entre las barras. El estudio se realiza mediante métodos numéricos con análisis no lineales y se comparan los resultados con ensayos de nudos y vigas en escala real en el laboratorio de grandes estructuras.
This work is part of a research project carried out at CECOVI within the Santa Fe Regional Faculty of the National Technological University. The use of truss beams designed with cold-formed C-section profiles has become popular in the country in small scale warehouse constructions. This work aims to analyze in detail the connection between bars, in cases where the diagonals are welded to the stiffening lip of the chord, forming a complex solution to evaluate by traditional means of analysis. At the same time, the solution does not use auxiliary connection means such as gussets plates, generating eccentricities at the meeting between the bars. The study is carried out using numerical methods with non-linear analysis and the results are compared with tests of full-scale nodes and beams in the laboratory of large structures.
