Elastoplastic behavior of welded connections in square section steel pipes submitted to monotonic load

This research aims to analyze the elastoplastic behavior of welded connections of square section steel tubes subjected to monotonic loading, by means of the theoretical - experimental comparative analysis of the distortion of the cross section geometry of the elements of the beam - column joint.

description	This research aims to analyze the elastoplastic behavior of welded connections of square section steel tubes subjected to monotonic loading, by means of the theoretical - experimental comparative analysis of the distortion of the cross section geometry of the elements of the beam - column joint. For the experimental tests it was necessary to build a rigid support frame designed with STAAD software. Pro v8i, of fixing and assembly to the gantries and load application system of the universal machine of the Materials Laboratory of the Faculty of Engineering of the University of Zulia. In every test a progressive load (monotonic load) was applied on the upper connection of the gantry to systematically to measure displacements and distortion of the geometry of the beam jointing elements column of the lower connection. While the theoretical model was performed using the finite element program [4] ANSYS Workbench. The obtained results show that: the welded connection presents a local failure by punching in the column that reduces the theoretical plastic moment capacity of the gantry "Mp" by 46%, scenario of concern for being this capacity used in the design under the theory Design for Load and Resistance Factors (LRFD). The welded connection (node) does not meet the weak beam strong column criterion established by Norma. The column of the welded joint must be reinforced to avoid the formation of the plastic ball joint and a possible mechanism of collapse in the gantry

Para los ensayos se construyó un marco soporte rígido diseñado con el software STAAD. Pro v8i, de fijación y ensamblaje a los pórticos y sistema de aplicación de carga de la maquina universal del laboratorio de materiales de la Facultad de Ingeniería de la Universidad del Zulia, Venezuela. Cada prueba consistió en imponer carga progresiva en la conexión superior del pórtico, para medir en desplazamientos y distorsión de la geometría de los elementos unión viga columna de la conexión inferior. El modelo teórico fue realizado utilizando el programa de elementos finitos ANSYS Workbench. Los resultados evidenciaron: la conexión soldada presenta falla local por punzonado en la columna, reduciendo la capacidad de momento plástico teórico del pórtico Mp en un 46%, escenario de preocupación por ser ésta capacidad utilizada en el diseño bajo la teoría Diseño por Factores de Carga y Resistencia. La conexión soldada (nodo) no cumple con el criterio columna fuerte viga débil establecido por la Norma COVENIN 1618:1998. La columna de la unión soldada debe ser reforzada para evitar la formación de la rótula plástica y un posible mecanismo de colapso en el pórtico.
