Nonlinear static methods may be not very effective in the assessment of 3D building structures because sometimes they do not provide an accurate estimate of the deck rotations. In order to overcome this shortcoming, the authors of this chapter proposed a nonlinear static approach for asymmetric structures that is performed applying the lateral force with two different eccentricities (named corrective eccentricities) with respect to the centre of mass of the deck. In this chapter the effectiveness of the corrective eccentricity method is verified with reference to four five-storey mass eccentric steel buildings in which the seismic force is sustained by frames equipped with buckling restrained braces.

Abstract

Nonlinear static methods may be not very effective in the assessment of 3D building structures because sometimes they do not provide an accurate estimate of the deck rotations. In order to overcome this shortcoming, the authors of this chapter proposed a nonlinear static approach for asymmetric structures that is performed applying the lateral force with two different eccentricities (named corrective eccentricities) with respect to the centre of mass of the deck. In this chapter the effectiveness of the corrective eccentricity method is verified with reference to four five-storey mass eccentric steel buildings in which the seismic force is sustained by frames equipped with buckling restrained braces.
