pruebas experimentales;, conexiones de acero;, pandeo localResumen
En este artículo se discute la respuesta sísmica de marcos de acero con conexiones de viga I al eje menor de la columna. Se realizaron pruebas experimentales sometidas a demandas cuasi-estáticas en escala natural. Las conexiones reportan una concentración de daño gobernada por el pandeo local de los patines, por lo que se analiza la distribución de esfuerzos y el fundamento de los criterios normativos para mejorar su respuesta. Los resultados experimentales se comparan considerando un modelo de elemento finito y modelos detallados de plasticidad distribuida en el programa OpenSees. Adicionalmente, se obtuvo la curva envolvente de las pruebas para calibrar los criterios normativos para la predicción inelástica en manuales especializados de análisis no lineal.
