SUMMARY The seismic reliability of two 24‐story buildings that have the same geometry and structural layout was evaluated and compared. The structural system of the first building consists of ductile steel braces and composite moment‐resisting frames (traditional building). The structural system of the second building consists of nonductile flexible steel frames stiffened through a system of buckling‐restrained braces (innovative building). Whereas the former was designed according to the Mexico City Building Code, the latter was designed according to a displacement‐based methodology. Both buildings were assumed to be located at the same site in the lake zone of Mexico City. The study shows that in spite of being considerably lighter, the innovative building exhibits higher levels of reliability. Copyright © 2011 John Wiley & Sons, Ltd.
