Título del libro: 9th Us National And 10th Canadian Conference On Earthquake Engineering 2010, Including Papers From The 4th International Tsunami Symposium Título del capítulo: Seismic reliability of two twenty-four story braced buildings: Evaluation and comparison. Part I.
The seismic reliability of two twenty-four story buildings that exhibit the same geometry and structural layout is 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 non-ductile flexible steel frames stiffened through a system of buckling restrained braces (innovative building). While the former was designed according to the Mexico City Building Code, the latter was designed according to a displacement-based design methodology and the concept of damage-tolerant structures. Both buildings are assumed to be located in the Lake Zone of Mexico City. The reliability study shows that in spite of being considerably lighter, the innovative building exhibits higher levels of reliability for three performance levels: serviceability, life safety and collapse prevention.
