ABSTRACT
The validity and applicability of the static pushover analysis have been extensively studied in literature. In particular, many researchers have compared the pushover curves with idealized envelopes obtained from incremental dynamic pushover analyses of structures subjected to artificial and natural input ground motions. Furthermore, the effectiveness of the Capacity Spectrum Method (CSM) has been validated by comparison with experimental results from pseudo-dynamic, cyclic and pushover tests. The Capacity Spectrum Method-by means of a graphical procedure-compares the capacity of the structure to resist lateral forces to the demands of earthquake response spectra. Different Nonlinear Static Procedures (NSPs) based on the CSM have been introduced in pre-standards reports and guidelines. Some of them were incorporated in the new generation of seismic codes to determine the deformation demand imposed on a building expected to behave inelastically.
