| Zusammenfassung |
On 8 November 1983 an earthquake of magnitude 4.6 damaged more than
16 000 buildings in the region of Liège (Belgium). The extraordinary
damage produced by this earthquake, considering its moderate magnitude, is
extremely well documented, giving the opportunity to compare the
consequences of a recent moderate earthquake in a typical old city of
Western Europe with scenarios obtained by combining strong ground motions
and vulnerability modelling.
The present study compares 0.3 s spectral accelerations estimated from
ground motion prediction equations typically used in Western Europe with
those obtained locally by applying the statistical distribution of damaged
masonry buildings to two fragility curves, one derived from the HAZUS
programme of FEMA (FEMA, 1999) and another developed for high-vulnerability
buildings by Lang and Bachmann (2004), and to a method proposed by Faccioli
et al. (1999) relating the seismic vulnerability of buildings to the
damage and ground motions. The results of this comparison reveal good
agreement between maxima spectral accelerations calculated from these
vulnerability and fragility curves and those predicted from attenuation law
equations, suggesting peak ground accelerations for the epicentral area of
the 1983 earthquake of 0.13–0.20 g (g: gravitational acceleration). |
