steel frames, earthquake demands, connections, experimental test, ductilityAbstract
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.
