Abstract

The Seismic Assessment of an asymmetric plan building is performed through an assemblage of recent Nonlinear Static Procedures (NSPs); some of them are extensions of known NSPs. Among these methods are included two multi-mode methods: Modal Pushover Analysis (MPA) and Improved Modal Pushover Analysis (iMPA); the Extended N2 which considers the higher modes effects in both plan and elevation; and the 3D Pushover wherein each step derives from a different known NSP in order to obtain the most reliable results.
The seismic response of an asymmetric plan building is studied considering both components of ground motion acting simultaneously. The seismic assessment of the building is performed in terms of pushover curves, top displacement ratios, lateral displacements profiles, interstorey drifts, normalized top displacements and shear forces. Such seismic quantities are compared with the results obtained by means of Nonlinear Dynamic Analysis (NDA).
