TAPIA HERNANDEZ, Edgar; SANTIAGO FLORES, Alejandro; GUERRERO BOBADILLA, Héctor  and  CHAVEZ CANO, Marcos M.. Experimental behavior of connections for steel frames under seismic demands. Ing. sísm [online]. 2020, n.103, pp.37-55.  Epub Feb 02, 2021. ISSN 0185-092X.  https://doi.org/10.18867/ris.103.562.

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.

Keywords : steel frames; earthquake demands; connections; experimental test; ductility.
