GARCIA CARRERA, Jesús Salvador  and  TAPIA HERNANDEZ, Edgar. Inelastic response of ductile eccentrically braced frames. Ing. sísm [online]. 2019, n.100, pp.51-70. ISSN 0185-092X.

In this paper, results of static and dynamic nonlinear analyses of 6- and 9-stories regular buildings structured with eccentrically braced ductile steel frames are discussed. The structures were analyzed through detailed models in OpenSees. The results underlined that mid-rise eccentrically braced structures designed in compliance with capacity design principles can develop undesired behavior, characterized by a damage concentration. In order to improve the knowledge acquired, parameters and inelastic capacities of the structural system were carefully assessed.

Keywords : Eccentrically brace; collapse mechanism; overstrength; ductility.
