Abstract
The main object of this investigation was to develop a pushover analysis
procedure for an existing building in order to define the expected seismic
performance and to verify a proposed mathematical equation that calculated the
plastic hinge rotations in order to simulate the inelastic behaviour of the building.
A series of tests have taken place in the past on the building in question.
Based on the results, a critical comparison of the local and global response
between the pushover analysis and the experimental data has been made. The
analysis results include a clear view of the seismic behaviour, the mechanism of
development of plastic hinges, the members and storeys with the maximum
vulnerability and the development of the inelastic dissipation mechanism.
This paper shows that, during a moderate earthquake, the pushover analysis
