raditional nonlinear static methods, e.g. the original version of the N2 method implemented in Eurocode 8, are not always effective in the assessment of asymmetric structures. To overcome this shortcoming, two methods have been recently suggested by Kreslin and Fajfar and by Bosco et al. In this chapter, the two improved nonlinear static methods and the original N2 method are applied to predict the maximum seismic response of three groups of single-storey systems. Further, the systems of each group are schematised by means of two different single-storey models. In the first model, a rigid deck is sustained by resisting elements, which provide lateral stiffness and strength along only one horizontal direction. In the second model, the resisting elements provide lateral stiffness and strength in all the horizontal directions and possess a bi-axial yield domain.

Abstract
raditional nonlinear static methods, e.g. the original version of the N2 method implemented in Eurocode 8, are not always effective in the assessment of asymmetric structures. To overcome this shortcoming, two methods have been recently suggested by Kreslin and Fajfar and by Bosco et al. In this chapter, the two improved nonlinear static methods and the original N2 method are applied to predict the maximum seismic response of three groups of single-storey systems. Further, the systems of each group are schematised by means of two different single-storey models. In the first model, a rigid deck is sustained by resisting elements, which provide lateral stiffness and strength along only one horizontal direction. In the second model, the resisting elements provide lateral stiffness and strength in all the horizontal directions and possess a bi-axial yield domain.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
