Evaluation of the seismic vulnerability of the buildings in the urban area of the district Chiquian, using the ArcGIS model builder

Abstract

The present descriptive, non-experimental and transversal investigation work has the
objective of evaluate the seismic vulnerability of the buildings of the urban area of the
district of Chiquian applying the AcrGIS model builder.
The proposed methodology allows the automation and the creation of a model of
seismic vulnerability using the ArcGIS model builder, where eleven parameters were
evaluated for the determination of the vulnerability index and the damage index in the
buildings of the urban area of the district of Chiquian.
Of an overall of 1417 buildings, it was found that the 14,7% of the houses are in low
vulnerability, the 21% in medium vulnerability, the 48,8% in high vulnerability and
the 15,2% in very high vulnerability. Besides, considering the vulnerability index and
a horizontal acceleration of the ground of 0,32 g, it was calculated that 1209 houses
(85,32%) suffered the total collapse and 208 houses (14,68%) will keep standing with
some structural damage. According to the index of calculated damage and considering
the price per square meter of building, if an earthquake would occur, with the
previously described characteristics
