A revised (PTVA) model for assessing the vulnerability of buildings to tsunami damage
The Papathoma Tsunami Vulnerability Assessment
(PTVA) Model (Papathoma, 2003) was developed in
the absence of robust, well-constructed and validated building
fragility models for assessing the vulnerability of buildings
to tsunami. It has proven to be a useful tool for providing
assessments of building vulnerability. We present an
enhanced version (PTVA-3) of the model that takes account
of new understanding of the factors that influence building
vulnerability and significantly, introduce the use of the Analytic
Hierarchy Process (AHP) for weighting the various attributes
in order to limit concerns about subjective ranking of
attributes in the original model. We successfully test PTVA-
3 using building data from Maroubra, Sydney, Australia
