000009874 520__ $$2eng$$aA study is made about the sensitivity of seismic reliability functions for multistory buildings, expressed in terms of Cornell’s reliability index β, to the criterion used to evaluate it (deformation capacity, secant-stiffness reduction index) and the type of structural arrangement. Results show that the reliability index β varies in a much faster way with the normalized intensity for a dual wall-frame system than for a frame system; this may be due to the fact that, in the former case, the lateral strength and stiffness are concentrated in the wall, while they are distributed among different structural members in the other case. Base-shear vs roof displacement curves obtained by pushover analysis may show large differences in the lateral strength remaining after the deformation capacity (that corresponding to a 20 percent reduction in the base-shear, with respect to its maximum throughout the curve) is exceeded. These differences partly explain the large differences in the values of β corresponding to given values of the ground motion intensity normalized with respect to the deformation capacity.
