Las configuraciones seleccionadas son ampliamente empleadas en estructuras de acero con marcos momento resistentes en la práctica mexicana. De acuerdo a los resultados, las conexiones ensayadas bajo grandes deformaciones inelásticas desarrollaron una concentración de daño inesperada que no es lo suficientemente dúctil para una estructura de acero de alta ductilidad. Se enfatiza el efecto de algunos parámetros de soldadura y detalles de fabricación que mejorarían la respuesta de las conexiones ante demandas sísmicas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Cyclic inelastic behavior of six beam-column connections experimentally tested through natural-scale models are discussed. Selected configurations are widely employed in moment-resisting steel frame structures by the Mexican practice. According to the results, tested moment-resisting connections under large inelastic deformations demands developed an unexpected damage concentration that is not enough ductile for a high-ductility steel structure. The effect of various welding parameters and fabrications details are emphasized in order to improve the response of the connections under seismic demands.]]></p></abstract>
